Will coppermine ........

[dfstrottersfan]

I have an application which really looks suited to Coppermine.

I want to load an image gallery  -  myself but allow only recognised users to access the gallery and read i.e. download the images.

Can anyone tell me if this is possible - I had a quick look at the documentation and it was not obvious to me if this was possible.

I didn't want to invest a lot of time if it was not possible

Thanks in advance

How can I let unregistered users see the thumbnails only, but not the actual pictures?

There is a variation on this posted on the boards to make it even more restrictive, or you could use album viewing rights to control access.

ok here's what we do:) this is VERY possible. although you must be willing to code ALL of this and to not hold me responsible if anything happans that shouldn't. (back up all the files that will be modifed)

First off, let's create a file called "images.php".

Place this code in it:

Note: That file has already been coded to NOT show images to users who are not logged in; therefore, your images are protected from that point.

Next, let's open up the file "functions.inc.php" in the /include folder.

Replace:

Code Select Expand

return $url_prefix[$pic_row['url_prefix']]. path2url($pic_row['filepath']. $pic_prefix[$mode]. $pic_row['filename']);

With:

Code Select Expand

       if (is_null($pic_row['pid']) || !isset($CONFIG['url_mode']) || $CONFIG['url_mode']!='hide')
       return $url_prefix[$pic_row['url_prefix']]. path2url($pic_row['filepath']. $pic_prefix[$mode]. $pic_row['filename']);
return 'get_file.php?pid='.$pic_row['pid'].'&size='.$mode;

Next, open up "config.inc.php" in the /include folder

Add this line to the code:

Code Select Expand

$CONFIG['url_mode'] = 'hide';

Okay, this will make all of the images in your gallery appear as: images.php?pid=(whatever it is)&size=(the size) instead of http://yousite.com/yourcpgdir/albums/whatever.jpg.

Next, open up the following files: index.php, displayimage.php, and thumbnails.php

To each file, add this code after "define('IN_COPPERMINE', true);"

Code Select Expand



include("include/init.inc.php");

if(!USER_ID){
header("Location: login.php?referer=$PHP_SELF");
exit;
}


There you go! It should work fine if you do it right, if you have any problems, post back!

Seems to me that all he'll need to do is make a custom bridge file. He didn't say he had cpg already installed.
