Installation

Was ist die Mindestvoraussetzung für die Installation und Verwendung von Coppermine 1.4.x ?



[nach oben]

Was ist ImageMagick und wie bekomme ich es?

GD ist eine graphical library, die es PHP ermöglicht Bilder zu bearbeiten. Wenn Du Deinen eigenen Webserver betreibst, dann kannst Du GD unter www.boutell.com/gd/ runterladen. Unter L(Unix) Systemen könnte es nötig sein, abhängig von der Apache Version, PHP neu zu kompilieren. Die meisten neusten PHP Versionen bringen GD direkt mit. Auf den meisten Windows Systemen kann GD direkt in der php.ini aktiviert werden. Wenn Du von einem Webhoster abhängig bist, dann überprüfe, ob GD/GD2 Unterstützung für Deine Seite zur Verfügung steht. Sollte das nicht der Fall sein, frage deinen Webhoster, ob Du es haben kannst oder Suche Dir einen Neuen. GD/GD2 sind meistens ein Standardfeature bei den meisten Webhostern.

Was ist GD und wie bekomme ich es?

ImageMagick ist eine andere graphical library wie GD/GD2 für die Bildbearbeitung. Solltest Du einen eigenen Webserver laufen haben, dann kannst Du es unter imagemagick.org runterladen. Dort sind Sources für Unix, Linux, Mac and Windows erhältlich, sowie binary packeges für verschiedene Server Betriebssysteme. Wenn man bei einem Webhoster ist, dann kann man ein ImageMagick installieren

Wie kann ich heraus finden, welche PHP Version ich benutze?

Wenn Du Coppermine noch nicht installiert hast, dann erstelle eine leere Datai mit dem Namen "info.php". Schreibe den folgenden Code hinein: <?php phpinfo(); ?>. Speichere die Datei und lade sie auf Deinen Server hoch; anschließend rufe die Datei in deinem Browser auf. (z.B. http://www.deinedomain.de/info.php). In der ersten Zeile ist die PHP Version zu finden "PHP Version X.Y.Z"
Bitte beachte: die info.php Datei auf Deinem Websever kann ein Sicherheitsrisiko sein; am besten nach Gebrauch läschen in ein Passwort geschütztes Verzeichnis verschieben!
 
Wenn Du bereits Coppermine installiert hast, dann findest Du eine phpinfo Datei (phpinfo.php) in den Coppermine Ordnern. Log Dich in Dein Coppermine Setup als Admin ein und tippe folgende URL in Deinen browser ein: http://deineadresse.tld/dein_coppermine_ordner/phpinfo.php .

Was ist der Unterschied zwischen GD1 und GD2?

GD2 ist eine aktualisierte Version von GD1 und als solche werden Bilder mit einer besseren Qualität erzeugt (Zwischenbilder und Thumbnails).

Hier ist ein Beispiel, genommen von w-nailer: about resizing
(Original Bildgröße: 1024 x 768 Pixel):
GD 1.8.4:
ImageCreate
ImageCopyResized
128 x 96 pixels
GD 2.0.1:
ImageCreateTrueColor
ImageCopyResampled
128 x 96 pixels
Upgrades der GD Lib nach dem Coppermine installiert worden ist hat keinen Effekt mehr auf Bilder, die bereits erstellt worden sind. Allerdings auf diese, die nach dem Upgrade erstellt werden. Nur Dein Webhoster kann GD Lib installieren oder verbessern, außer wenn Du Deinen eigenen Webserver hast!

Wie sind die einzelnen Schritte um Coppermine zum laufen zu bekommen?

Wie in der Coppermine readme Datei genannt:

  1. Coppermine herunterladen
  2. Auf Deiner Festplatte entpacken
  3. Den Inhalt des Coppermine Ordners auf Deinen Server hochladen (Du kannst es im Wurzelverzeichnis oder einem anderen beliebigen Ordner installieren).
  4. CHMOD (CHange permission settings MODe) Deine neu hochgeladenen Coppermine "include" and "albums" Ordner und Unterordner um Schreib- und Leserechte zu setzen. Wenn Dein Webhoster keine Dateiverwaltung anbietet um die Rechte zu setzen, dann musst Du im Netz nach einem ftp Programm suchen, es downloaden und installieren um diese Aufgabe zu erledigen.
  5. Erstelle eine Datenbank, wenn noch keine vorhanden ist. Du brauchst keine Tabellen in Deiner neuen Datenbank zu erzeugen. Dies wird Coppermine für Dich tun. Wenn Du bereits eine Datenbank auf Deiner Website hast, dann kann Coppermine auch diese nutzen.
  6. Wenn Du auf einem Yahoo Webserver installierst, dann lies zuerst das.
  7. Rufe mit Deinem Browser die Adresse http://www.deineseite.de/coppermine/install.php auf und folge den Anweisungen der Installationsdatei (Hier werden die mySQL Tabellen erstellt und mit den Standardwerten aufgefüllt)
  8. Nach erfolgreicher Installation lösche die install.php Datei von Deinem Webserver.
  9. Rufe mit Deinem Browser http://www.yoursite.com/coppermine/ auf und melde Dich als Admin an, indem Du Benutzername und Passwort, die Du bei der Installation angegeben hast, eingibst. Klicke im Adminmodus auf CONFIG um deine Coppermine Fotogalerie einzurichten.
  10. Experimentiere mit Deiner Installation herum, erstelle neue Kategorien, Unterkategorien und Alben. Lade ein einige Bilder hoch (noch nicht zu viele), und teste, ob alles funktioniert.
  11. Rufe mit Deinem Browser die Seite http://www.deineseite.de/coppermine/docs/ auf und LESE die Dokumentation. Die Dokumentation hilft dabei Deine Fragen zu beantworten und Probleme zu lösen, so dass die Seite all Deinen Wünschen entspricht. Das Lesen der Dokumentation wird einige Minuten in Anspruch nehmen. Die Problemlösung kan sogar Tage oder Wochen in Anspruch nehmen
  12. Wenn Deine neue Coppermine Installation in einem Unterordner auf Deiner Seite ist, dann veröffentliche diese indem Du auf diese verweist.

Wie kann ich ImageMagick oder GD installieren?

Du kannst nur ImageMagic oder GD installieren, wenn Du Deinen eigenen Server laufen lässt oder Du hast shell Zugriff auf Deinen Webserver. Wenn Deine Seite bei einem Webhoster liegt, dann kann st Du nur Kontakt zu ihm aufnehmen und fragen, ob er die Erweiterungen für Dich installiert. Sollte das nicht klappen, dann wähle einen anderen Anbieter.

Ich habe geringe Speicherplatzkapazität. Gibt es eine "Minimum Installation"?"?

DAs ist natürlich ein Widerspruch in sich: Eine Galerie laufen zu haben bedeutet normalerweise, dass außreichend Speicherplatz für Bilder vorhanden sein muss, aber wenn Du auf dem geringen Speicherplatz, der Dir noch übrig bleibt, nur ein paar wenige Bilder veröffentlichen möchtest, dann gibt es schon ein paar Dateien, die Du (falls nicht benötigt) nicht dochzuladen brauchst oder löschen kannst. Es ist trotzdem empfehlenswert, dass nur erfahrende Benutzer eine Minimuminstallation erstellen. Bei Zweifel besser eine Komplettinstallation machen!

  1. Beseitige alle Sprachen, die Du nicht benötigst (Wenn alle Benutzer aus dem gleichen Land kommen).
    Es ist empfehlenswert für Dich als Admin Englisch zu behalten, auch wenn alle Benutzer andere Sprachen benutzen, damit Du ab und zu die Englische Sprachdatei nutzen kannst.
    Lösche alle Dateien aus dem lang-Unterordner Deiner Coppermine Installation, außer DeineSprache.php (z.B. wenn Du Deutsch nutzt, lösche alle Dateien außer /lang/german.php und /lang/german-utf-8.php).
    Eingesparter Speicherplatz (maximal): 2.9 MB
  2. Beseitige alle Sprachen mit einer Enkodierung, die Du nicht benötigst.
    You'll notice that for each language there are two files in the lang-folder: yourlanguage.php and yourlanguage-utf-8.php. You will need the utf-8 files only if you chose "Unicode(utf-8)" in "Character encoding" on your config page. Using Unicode (utf-8) will display the gallery in the language your page visitor has set in his browser. If you haven't chosen Unicode (utf-8) in coppermine config, it's safe to delete all language files with "utf-8" in their filenames from the lang folder.
    Webspace that can be saved (maximum): 1.7 MB
  3. Remove all unnecessary themes
    Remove all themes you won't use from your themes folder. If you're using a customized theme, it's recommended to leave the classic/default theme in place for administrative purposes.
    Example: if you're using the theme "Eyeball" that comes with coppermine, you can safely delete the sub-folders "classic", "fruity", "hardwired", "igames", "mac_ox_x", "project_vii", "rainy_day", "styleguide" and "water_drop" from your themes folder.
    Webspace that can be saved (maximum): 1 MB
  4. Remove some docs from the docs folder
    The docs folder contains documents that are meant to help you set up and administer coppermine. In cpg1.4.0 or better, there are some files in this folder that are mandatory to have on the server for the help icons to work; others are optional. You can remove the files "credits.html", "faq.html", "README.html", "theme.htm" and "translation.htm". All other files (and the subfolder "pics") have to remain on the webserver if you want to use the help icons (recommended).
    Webspace that can be saved (maximum): 164 KB
  5. Remove bridge files
    The Coppermine package includes bridge files used for integration of coppermine with bulletin board software like phpBB, SMF etc. It is safe to delete some files in the bridge folder; if you are using bbs integration, you will have to keep the bridge file that corresponds to the bbs you're using. If you are not using integration, you must keep the file coppermine.inc.php. The file udb_base.php is required under all setups ans should not be deleted.
    Webspace that can be saved (maximum): 85 KB
  6. Remove the flags
    If you're not going to use the "select language by flags" option from the coppermine menu, it's safe to delete the flags folder (/your_coppermine_folder/images/flags/). If you are using the flags option, you can of course delete all flags you don't use at all.
    Webspace that can be saved (maximum): 80 KB
  7. Remove files that are needed for install or upgrade only
    Once Coppermine has been installed and is "up-and-running", you can safely delete the files that are needed for installing only: from the coppermine root folder, delete install.php, installer.css, update.php, upgrade-1.0-to-1.2.php. You can delete the folder "sql" as well.
    If you want to update/upgrade your coppermine install later (once a new version comes out), you will of course have to re-upload the update files and the sql folder to your webserver.
    Webspace that can be saved (maximum): 73 KB
  8. Choose to only display intermediate-sized pics and thumbnails.
    After you have batch added your pics and confirmed that they are displaying properly in your CPG setup, click on Admin Tools and select the "Delete original size photos (1)" option.

Summary: a minimum install of coppermine will need approx. 3.3 MB of webspace.

Upload

General Upload Troubleshooting

When troubleshooting uploads in CPG 1.4, you are advised to change the upload settings in the Groups console to 'Single uploads only' and to activate 'Debug mode' in the config console. Changing this setting negates some of the error masking done in the multiple upload setting. This will allow you to access more detailed error messages.

First and foremost:Check your folder and file permission settings on the /albums, /albums/userpics, and /albums/edit directories. All should be 777 or 755.

If you don't know what we mean by 777 or 755, you need to do a Google search on UNIX file permissions. Windows has a similar set of file permissions. You can usually set these permissions using an FTP client (If you don't know what an FTP client is, Google for FTP client).

For those of you who skim over statements written in red letters, I will repeat to try to get your attention:

Yes, we are writing about something that could easily apply to YOU.
 
We repeat -- check your permissions on the /albums, /albums/userpics, and /albums/edit directories. All should be 777 or 755.
 
Yes, we do want you to check the permissions of each folder even if you think you have already done this. Yes, we mean it.

NOTE: HTTP uploads are limited by the restrictions placed upon them in PHP's configuration.


 
Things to check: (if you are webhosted, you will need to consult with your webhost regarding the following settings.)
  1. max_input_time- 60 seconds is the default time limit for uploading files.
    This time limit includes the time it takes for the files to upload, so if you exceed this limit, the file will not even parse, and the browser will not get a response. You can workaround this by trying to upload smaller or fewer files, or you can try uploading over broadband. The best solution, of course, is to increase the time limit to something more in line with your needs.
  2. upload_max_filesize - 2MB is the default limit for individual files.
  3. post_max_size - 8MB is the default limit for post requests.
  4. memory_limit - 8MB is the default size.
  5. PHP's LimitRequestBody - 512KB default limit. (mainly an issue on Redhat/Apache systems. Found in /etc/http/conf.d)
    In general, upload_max_filesize < post_max_size < memory_limit in order for uploads to function properly. Coppermine may warn you if a file exceeds upload_max_filesize, but it cannot warn you if the total size of all the files exceeds the post limit or the memory limit.
  6. file_uploads - This determines whether or not PHP will allow file uploads. It must be set to "On".
  7. upload_tmp_dir - This specifies the temporary directory where PHP stores uploaded files.

The most common issue caused by this setting is an open_basedir warning. In this situation, your server administrator has restricted the files that PHP can work with to a certain directory. If he does not create and specify a temporary directory within the open_basedir restriction, PHP will attempt to use the OS temporary directory, and it will be rebuffed by the open_basedir restriction.

Some notes about the different types of upload mechanisms available in CPG 1.3 (or better):
Multiple HTTP uploads are designed to handle a small number of files, and have an upper limit of 10 files at a time. Therefore, they are not well suited for the uploading of large numbers of files unless you are running your own webserver or have control over the php.ini configuration.
If you are looking to upload more than 15 or 20 files at a time, you should consider the batch add process or the XP_Publisher utility. Each has its own drawbacks and advantages.
The batch add process is fast, but it creates quite a load on the server and, as a result, you may experience timeouts causing your uploads to terminate prematurely. XP Publisher, on the otherhand, is considerably slower, but it limits the load on the server. It also circumvents many of the pitfalls caused by limitations set in the php.ini configuration by uploading each file in the batch being uploaded as an individual post request.

Error Messages

When installing I get the error Fatal error: Call to undefined function: imagecreatefromjpeg() in /include/picmgmt.inc.php on line 168. What does that mean?

This error means that the version of PHP installed on your server does not support the GD1/GD2 image library.
If you know that the ImageMagick suite is installed on your server, you could try using it instead. Otherwise, you will have to find another webhost or convince your existing webhost to have GD1/GD2 installed (the GD image library is now a standard component of PHP and should normally be installed and available, de facto). Coppermine won't run without gd or image magick.

When installing I get the error Warning: mkdir(dummy) [function.mkdir]: Permission denied in /your/path/to/coppermine/install.php on line 126. What does that mean?

The script must have the right to create and delete files.

I get the error "Warning: Empty Delimiter in search.inc.php line 33". What can I do?

Edit the file include/search.inc.php
Look for the line with
$charset = $CONFIG['charset'] == 'language file' ? $lang_charset : $CONFIG['charset'];
Replace it with :
$charset = $CONFIG['charset'] == 'language file' ? $GLOBALS['lang_charset'] : $CONFIG['charset'];

I get the error Zero Sized Reply during install. What can I do?

On rare ocassions, some users experience this error message during install:

While trying to retrieve the URL: http://yoursite.com/coppermine/install.php
The system returned:
Zero Sized Reply
Reason:
The remote server did not reply any data for this request.
Please try again later
Unfortunately, we still do not know why this happens - those who get this error simply cannot use Coppermine (our apologies). Disabling or removing HTTP filtering on the firewall may help (client and/or server end). Should you have any idea as to what may be causing this error (and even possibly come up with a solution), please visit the Coppermine support board and enlighten us.

I have the error message Warning: Undefined index: SCRIPT_NAME in /www.your-domain.com/include/init.inc.php on line 90. What can I do?

Try to edit the file include/init.inc.php:
change

$PHP_SELF = isset($_SERVER['REDIRECT_URL']) ? $_SERVER['REDIRECT_URL'] : $_SERVER['SCRIPT_NAME'];
to
$PHP_SELF = $_SERVER['PHP_SELF'];

When a user tries to upload a picture s/he gets the error message Impossible to move somepic.jpg to albums/userpics/ | Warning: move_uploaded_file(/tmp/phpezCYKr) [function.move-uploaded-file]: failed to create stream: Operation not permitted. What's wrong?

You should contact the admin of your webhost because you usually can't change the location of the website's temporary directory for file uploads, yourself (it is part of PHP configuration) .
If the open basedir restriction is in effect on your site then the temp directory for file uploads should be one that you can access.

When uploading I get the error Warning: Undefined variable: HTTP_POST_VARS in include/init.inc.php on line 43. What can I do?

Check if your version of PHP fullfills the minimum requirements for Coppermine. If your version is 4.1.0 or better, then this error is probably caused by a misconfiguration of your hosting server, and not a Coppermine issue. If the server isn't yours to configure properly (that is: if you're with a webhost), you can try this workaround (at your own risk):
Edit the file "init.inc.php" and look for

$PHP_SELF = isset($_SERVER['REDIRECT_URL']) ? $_SERVER['REDIRECT_URL'] : $_SERVER['SCRIPT_NAME'];
Replace it with
$PHP_SELF = $_SERVER['PHP_SELF'];

I get the error message Can't create/write to file '/tmp/#sql_45d5_0.MYI'. What's wrong?

The problem:
MySQL can't create a temporary file for the result set in the given temporary directory.

The solution:
Alter the tmpdir variable to point to a writable directory. It requires changing the tmpdir line in the my.cnf file, usually in the [mysqld] section (tmpdir = /writable/dir, where /writable/dir is a directory to which you can write).

Ask your webhost to make the above changes.


[nach oben]

I get the error message Can't open file: 'yourPrefix_tableName.MYI' or similar. What's wrong?

The problem:
Your table is corrupted.

The solution:
This is not a coppermine issue, but a mySQL issue. It just may affect a database table used by Coppermine.
Use your website's Control Panel to repair the table, or use phpMyAdmin to execute this sql query: REPAIR TABLE yourPrefix_tableName
(Replace yourPrefix_tableName with your table name, e.g. cpg145_pictures)

If you don't understand the solution, ask your webhost to make the above changes.

I don't want to show the last uploads and/or random pictureson the start page. How do I edit what's shown on the start page of coppermine?

  1. login as admin into your CPG setup
  2. click on "Admin Mode" if it is not already enabled
  3. Click on Config in the "Admin Menu"
  4. under "Album list view" use the above provided keywords: (e.g. anycontent/catlist/alblist/random,2/lastup,2 translates to: "anycontent file contents, category list, album list, 2 rows of random pics, 2 rows of last uploads" -- and will display in the order that they are listed)

How do I remove/edit the bottom line "Powered by Coppermine" ?

You mustn't remove the line - it's part of the deal: you're allowed to use and modify Coppermine on your site, but this line must remain! We feel strongly that it is more than a justified demand to give credit where credit is due. We hope that you will agree with us and just be glad that such a great piece of software is available for use at NO COST, with no banner ads or embedded spyware, to you.
You are allowed to change the way the line looks by editing the CSS class to make it fit into the design of your site; edit /themes/yourtheme/style.css, look for the class "Footer" and change the settings there as you wish.
Note: PLEASE don't ask idiotic questions on how to remove this line in the Coppermine Photo Gallery Support Board - your posting will be deleted!

I want to buy a license for Coppermine (and get rid of the "Powered by Coppermine" line). How?

As Coppermine is based on OpenSource software published under GNU/GPL (which allows the modification of the code, but disallows changes of the license model of your modifications), you can not purchase a version of coppermine with or without the credit line removed. Read the file COPYING that comes with the distribution of Coppermine for details.

I don't want to use the feature XYZ of Coppermine. How can I remove it?

Just remove the link; edit /themes/yourtheme/theme.php, look for the feature you want to remove and comment out the HTML code.
Example: if you want to remove the ecard-feature, just look for

<td align="center" valign="middle" class="navmenu" width="48">
<a href="{ECARD_TGT}" title="{ECARD_TITLE}">
<img src="images/ecard.gif" width="16" height="16" border="0" align="absmiddle" alt="{ECARD_TITLE}"></a>
</td>
and replace it with
<!--<td align="center" valign="middle" class="navmenu" width="48">
<a href="{ECARD_TGT}" title="{ECARD_TITLE}">
<img src="images/ecard.gif" width="16" height="16" border="0" align="absmiddle" alt="{ECARD_TITLE}"></a>
</td>-->

How can I backup my coppermine database?

Currently, there are no built-in backup solutions for coppermine available, yet. To backup your directory/file structure, you must use the good old ftp method and a tool like phpMyAdmin to backup your database (Many webhosts that offer mySQL also offer a pre-installed version of phpMyAdmin - if so, use that!). PhpMyAdmin is easy to install: just download the distribution, unzip it to your harddrive, edit one config file and upload it to your server. (NOTE: Some webhosts offer backup services. You should check if this service is available to you, first.)

Here's a quick "how to backup a database with phpMyAdmin" primer:

The fullsize-pic doesn't pop up when clicking on the intermediate size pic. What's wrong?

If you are certain that your original file is larger in dimensions than the settings you selected for intermediate sized pictures, there's a good chance that you over-edited your theme's template/html file: make sure that the line <script type="text/javascript" src="scripts.js"></script> inside /themes/yourtheme/template.html is still there to make the pop-up window work...
The <head>-part of your template file should look like this:

<head>
<title>{TITLE}</title>
<meta http-equiv="Content-Type" content="text/html; charset={CHARSET}" />
{META}
<link rel="stylesheet" href="themes/default/style.css" />
<script type="text/javascript" src="scripts.js"></script>
</head>
- If you're still unsure about this, just compare your theme's template.html with the default theme that comes with coppermine .

How can I prevent other sites from linking directly to the pictures in my gallery instead of the gallery page?

IF your webhost supports the use of .htaccess files (you will need to ask them), you can prevent "hotlinking" by creating an .htaccess file in the albums folder.
Open your text editor and add the following lines, then save the file as .htaccess :

SetEnvIfNoCase Referer "^http://www.yourdomian.com/" locally_linked=1
SetEnvIfNoCase Referer "^http://yourdomain.com/" locally_linked=1
SetEnvIf Referer "^$" locally_linked=1
<FilesMatch "\.(gif|png|jpe?g)$">
  Order Allow,Deny
  Allow from env=locally_linked
</FilesMatch>
This will only work on linux/unix and apache servers AND only if you're allowed to use /htaccess files by your webhost or if you run your own server and "mod_rewrite" is enabled on your server .

I tried to change the language on the config page, but it doesn't work. What's wrong?

"Character encoding" is probably set (or has been set sometime ago) to UTF-8 on your config page.
When UTF-8 is selected, Coppermine chooses your language file based on your browser configuration and stores the value in a cookie. This overrides the value stored in the CONFIG.
To fix that:

I can't upload with the upload feature. What's wrong?

If you experience the error message: No picture was uploaded. If you have really selected a picture to upload, check that the server allows file uploads..., check if there's a problem with HTTP uploads on your server - this feature may have been disabled or improperly configured. In phpinfo(), check that "file_uploads" is ON, "upload_max_filesize" is something like 2M and "upload_tmp_dir" is a valid directory!

I can't delete a certain picture with ftp. What can I do?

If you can't delete a file or picture with your FTP software, it is not Coppermine that won't allow you to delete the picture; it is your FTP server. The problem is in the configuration of your server. Try to delete your picture from within the script.

If PHP on your server is running under user "nobody," then all files created by any PHP script (this is not specific to Coppermine) will be owned by "nobody". There is no way to change that.

IMPORTANT: 0777 (CHMOD 777) should not be the default mode for directories because it may present a security risk, if your gallery is running on a shared server and PHP safe mode is not enabled, anyone with an account on the same server could possibly delete your pictures. There have been several threads on this issue on the Menalto Gallery forum and several users have seen their gallery hacked and destoyed because of this. This issue is not specific to Photo galleries, it applies to all PHP scripts that create directories. As long as someone has write access to a directory, s/he could conceiveably delete any file it contains, even if that person doesn't have write access to the file itself.
 
We would prefer to have users complaining LOUDLY and REPEATEDLY that they have to constantly contact their sysadmin to set this or reset that or even uninstall Coppermine, and have THIS as an issue and electing to switch to another gallery script because of this inconvenience, rather than learn of one person devastated in finding that all his/her pictures have been erased by a hacker.
 
Don't agree? Read this:
http://www.zend.com/manual/function.mkdir.php
http://www.zend.com/manual/function.chmod.php
before thinking of posting an argument in this forum.
 
Ultimately it is the decision of the sysadmin on how s/he will elect to run PHP as an Apache module and if all files/dir created by PHP are to be owned by "nobodyquot;. So sysadmins who have set up their servers as such, are in no position to complain when asked to remove certain files or directories.
 

On the webhost this site is running on, everything works fine when directory are created with mode 755 and all files/dir created by PHP are owned by the chezgreg user which is the user I use when connecting by FTP. Also if one of the file/directory on my site has a mode of 777, the server will shutdown my site and send me an email warning me that this is unsafe.

Why would you want to do that? Deleting the intermediate pics would disable many of the great features that make coppermine what is today. The option to send ecards, to add comments to pics, to rate pics, to display exif information, just to name a few. If you really want to save space, opt to delete your original files using the Admin Tools menu option. Doing this will allow your users to enjoy all of coppermine's features with the exception of viewing full-sized images. In the end, it will probably save you more space as well. Just be sure to set your intermediate sized picture settings in CONFIG to a size that you can live with.

If you really must remove the intermediate sized pics, search the mods and hacks board in the coppermine forum to learn how.

How do albums and folders work in coppermine?

  1. When you create an album, it is a dynamic 'virtual' album. Coppermine doesn't create a physical folder for this album on the server's hard drive, it leaves the pictures where you put them on the server, and uses the database to know which pic belongs in which album. You can move pics from album to album in Coppermine, but it's all done in the database, the pics are never moved on the server.
  2. When you upload by html, using the 'upload' link, coppermine places the pic (and the thumb and normal size copies) in the 'userpics' directory.
  3. When you upload by ftp, you should place the pics into folders that you create within the 'albums' folder, but never in the 'userpics' folder. The 'userpics' folder is reserved for html uploads only. You can create as many folders/sub-folders for FTP uploads as you want. (Many webhosting services will recommend that you keep the number of files per folder under 500 in order to maximize speed and certain functions. This means you can upload up to 500/3 files in each folder.) You can name these folders anything you want, but we do recommend mirroring the category/album structures that you have created, whenever possible, to facilitate ease of use and site management.
  4. When you batch add files that you have already FTP'd to your site, coppermine asks you what album you want to put the pics in, but it leaves the pics where they are on the server.

How do I show the same file in multiple albums?

The Album Keyword in Album Properties is used to link images from one album into another. Using this method, files/images can be displayed in various albums while the file itself need only exists in one album on your webserver. You simply upload a file to one album as you would normally do, then assign one or more keywords to the file. The keyword function reads blank spaces between words as a 'break' and assumes that these words are separate words. If you must use phrases for your keywords, connect them with an underscore or by using the ascii space holder ctrl+Alt+0160 (NOTE: the latter option only works with latin based character sets.) Each album can only have ONE (1) keyword or keyword phrase. All pictures residing in different albums that you would like to be displayed in this album must have the same keyword or keyword phrase in their respective keyword fields. Pictures, unlike albums, can have multiple keywords or keyword phrases separated by spaces. This provides you with the option to display pictures in many albums. For the visitor of these albums, it will appear as if the file/image had been uploaded to each.

If you use album keywords to display images/files in more than one album, enabling the Config option, Show number of linked files, will display additional information for the album stats. That is, if an album doesn't only contain "regular" files, but files linked via the "album keyword" option as well, the number of linked files will be displayed separately like this "3 files, last one added on Oct 07, 2004, 3 linked files, 6 files total".

Add-ons / Modifications / Hacks

How can I change the order of the pics when editing them?

By default, the pics are shown alphabetically when you edit them. To change the sorting order to "by date", edit editpics.php and change
$result = cpg_db_query("SELECT * FROM {$CONFIG['TABLE_PICTURES']} WHERE aid = '$album_id' ORDER BY filename LIMIT $start, $count");
to
$result = cpg_db_query("SELECT * FROM {$CONFIG['TABLE_PICTURES']} WHERE aid = '$album_id' ORDER BY pid LIMIT $start, $count");

How can I create a menu that's shown on the right side of the gallery?

When the template.html is read, it is split in 2. What is before the {GALLERY} tag is output by the pageheader function, what is after by the pagefooter function.
If your menu is in the "footer" you need to modify your theme.php file

   $template_vars = array(
      '{LANG_DIR}' => $lang_text_dir,
      '{TITLE}' => $CONFIG['gallery_name'].' - '.$section,
      '{CHARSET}' => $CONFIG['charset'] == 'language file' ? $lang_charset : $CONFIG['charset'],
      '{META}' => $meta,
      '{GAL_NAME}' => $CONFIG['gallery_name'],
      '{GAL_DESCRIPTION}' => $CONFIG['gallery_description'],
      '{MAIN_MENU}' => theme_main_menu(),
      '{ADMIN_MENU}' => theme_admin_mode_menu()
   );

   echo template_eval($template_header, $template_vars);
will become
   $template_vars = array(
      '{LANG_DIR}' => $lang_text_dir,
      '{TITLE}' => $CONFIG['gallery_name'].' - '.$section,
      '{CHARSET}' => $CONFIG['charset'] == 'language file' ? $lang_charset : $CONFIG['charset'],
      '{META}' => $meta,
      '{GAL_NAME}' => $CONFIG['gallery_name'],
      '{GAL_DESCRIPTION}' => $CONFIG['gallery_description'],
   );

   echo template_eval($template_header, $template_vars);
and
echo $template_footer;
will become
   $template_vars = array(
      '{MAIN_MENU}' => theme_main_menu(),
      '{ADMIN_MENU}' => theme_admin_mode_menu()
   );

   echo template_eval($template_footer, $template_vars);

How can I prevent unregistered users from viewing the gallery?

In Config, when "Allow unlogged users (guest or anonymous) access" is set to "No", unlogged users (i.e. guests or anonymous users) can not access anything in your gallery except the login screen (and the registration screen, if you allow registrations). Completely disabling anonymous access will probably decrease your site's popularity. Use this option only if you need your gallery to be absolutely private. The recommended setting is to leave anonymous access enabled and use the more specific permissions by groups and albums settings instead.

How can I display the name of the uploader with the picture info?

Warning: this is quite a complicated hack for a newbie to perform! Make sure to back up your original files before attempting this.
Edit displayimage.php and search for:
$info[$lang_picinfo['Filename']] = htmlspecialchars($CURRENT_PIC_DATA['filename']);
add after it:
$info[$lang_picinfo['Username']] = htmlspecialchars($CURRENT_PIC_DATA['user_name']);.
Then open /include/functions.inc.php and search for following in function get_pic_data():
if($select_columns != '*') $select_columns .= ', title, caption';
and replace it with:
if($select_columns != '*') $select_columns .= ', title, caption, user_name';.
After that search for:
$result = cpg_db_query("SELECT $select_columns from {$CONFIG['TABLE_PICTURES']} WHERE aid='$album' $approved $ALBUM_SET ORDER BY $sort_order $limit");
and replace it with:
$result = cpg_db_query("SELECT $select_columns from {$CONFIG['TABLE_PICTURES']} AS p LEFT JOIN {$CONFIG['TABLE_USERS']} AS u ON u.user_id = p.owner_id WHERE p.aid='$album' $approved $ALBUM_SET ORDER BY $sort_order $limit");
Then you have to add the language string for the username. Open /lang/yourlang.php and search for:
$lang_picinfo = array(
and add after that:
'Username' => 'Username',
Also you need to execute this query in MySQL (with a tool like phpMyAdmin):
ALTER TABLE `cpg11d_pictures` ADD INDEX ( `owner_id` );
(NOTE: If your database table_prefix is not "cpg11d_", you will need to change it in the query)

How do I enable clickable links in custom user fields?

Edit displayimage.php and change
$info[$CONFIG['user_field'.$i.'_name']] = make_clickable($CURRENT_PIC_DATA['user'.$i]);
into
$info[$CONFIG['user_field'.$i.'_name']] = bb_decode($CURRENT_PIC_DATA['user'.$i]);
 
This will allow you to use BBCodes in the custom fields: you can then have something like
[url]http://www.somesite.com/foo/bar.php?whatever=42[/url]
or
[url=http://www.somesite.com/foo/bar.php?whatever=42]link to some site![/url]
in your custom user fields (the display of which, of course, has to be enabled in the config page, begin with).

Common PHP errors and how to get rid of them...

There are a lot of people (especially PHP newbies) that post questions like I get the error "Parse error: parse error in XXX" and don't know what to do about it. That's why I translated this list of common errors (and a solution how to fix them) from the original german article in Dr. Web :

Can I rename template.html to template.php to include PHP code in my template?

No, this is simply not the way coppermine works; for "normal" pages the name of the extension tells the webserver whether the file should be parsed by the PHP interpreter. The template files within the themes folder are not being parsed this way - the extension .html was just chosen to make editing easier. You can not have PHP code in the template file, no matter how you name it - that's all there is to it!

I'm running my own server

How do I enable gd on my Windows server?

GD 1.x 2.x are normally part of all standard PHP distributions under Windows
To check if you have it, go to the directory where you installed PHP, go to the "extensions" subdir and see if you have a file named "php_gd2.dll".
Ocassionally, you will also need to edit your php.ini file (located in windows directory normally) and remove the ";" that is at the beginning of the line:
extension=php_gd2.dll (at the end of the file). This will cause PHP to load the GD2 extension.
Whenever you make changes to php.ini, remember that you will need to restart your webserver before changes become effective.

How do I enable ImageMagick on my Windows server?

ImageMagick is quite complicated to set up on Windows. There are several things to be taken into account. The Coppermine support board is not the right place to ask for help on installing it, as it deals with Coppermine, not "How to set up a server" (most people on the Coppermine boards don't run their own webserver, but they have webspace by a webhost). Instead, try to find support boards on the internet that deal with this special topic.

Coppermine Support board

These are (alas) not-so-frequently-asked-questions on the support board. Before posting on the Support board (or, in fact, any board), please read this:

I don't know PHP/mySQL...

No problem with that, everyone stars as a newbie. Just don't start each and every posting by stating "I'm a newbie", "I don't know anything about PHP" etc.
Usually, one can acertain that from your question itself. There's no need to apologize. Most of us can still remember when we were in your shoes.

I've posted my question a while ago, but nobody answers. What the...?

The support board is not a hotline. Although there are many visitors to the site, only a few do actually support - on a unpaid, voluntary basis. Yes, we don't receive remuneratio for our contributions and we each have a life, a job, family and more. We are away sometimes, as well. So, please, be patient, read the docs and search the boards while you are waiting.

If you are posting in the English support boards, pPlease do not post in some other language - in this way, others may benefit from your question (and the answers you receive ), too. Don't be afraid to write "poor english" - no one will laugh at you, and most of our visitor's first language isn't english to begin with! There's a german support board available at http://forum.the-service.de/ - use it if you are more comfortable with German and you' not able to write in English!

We have language-specific support boards for Chinese and French.
