Permanant watermark with undo possibility (GD2+IMagick)

[Stramm]

OK, lol...just for you I've installed this modmod on my test machine....

it's one lil mistake. Happened cause I'm already using a modded upload php

so here you go... find in upload php

Code Select Expand

   $form_array = array(
   array($lang_upload_php['album'], 'album', 2),
   array($lang_upload_php['pic_title'], 'title', 0, 255, 1),
   array($captionLabel, 'caption', 3, $CONFIG['max_img_desc_length']),
   array($lang_upload_php['keywords'], 'keywords', 0, 255, 1),
   array('control', 'phase_2', 4),
   array('unique_ID', $_POST['unique_ID'], 4),

I've corrected this above as well

Your method works like a charm! Everything is OK and I am quite pleased with the result.

Only one question. Can I apply the watermark to the already uploaded pictures?

Your method works like a charm! Everything is OK and I am quite pleased with the result.

Only one question. Can I apply the watermark to the already uploaded pictures?  

yes... try the admin tools -> Update thumbs and/or resized photos -> Both normal and full sized (if a orig copy is available)
the standard coppermine function isn't that good if you have loads of pics. If you do have more then ~500 tell me and I'll post my batch modify mod

[xb00t]

It seems to be working pretty fine except the fact that for some reason I cant change the CHMOD to some of my pics and CPG can't update them. It works works for some of them. @_@ The wierdest thing is that my FTP client wont change the CHMOD aswel. And I am root.

[Joachim Müller]

if you're root, you should know: CHOWN before CHMODing...
However, the root account shouldn't be used for FTPing.

[Stramm]

However, the root account shouldn't be used for FTPing.

for security reasons you should go even further and configure root not to be able to login using ftp, ssh, ssh2 or whatever. Most secure is to use a standard user to login and then su. This way an attacker will need to break two walls

And some FTP clients have problems with chown, chmod. Use ssh, that works

[Ancyru]

There seems to be an issue with having watermarks on Resized images only. I have added this mod to an unmodified coppermine 1.3.3

It works fine if I select watermarks for both images but no watermark appears for just resized images. Any suggestions?

[Ancyru]

Also when I select the option to watermark the originals only it watermarks the resized and original image.

[Stramm]

you're right... thanks for mentioning it. Looks like with the last bugfix a few if statements mixed up

just replace your picmgmt.inc.php with the new one

[Stramm]

That's a lil hack for the watermark mod. If you want certain users to have their own watermark then it's for you

How to use it?
Just FTP a new watermark file into the dir where your main watermark file already is. It's name should be the username it is for. On nix boxes it's case sensitive. It has to be png.
Eg. the user you want to have an own watermark for is 'MadDog'... then the watermark file needs to be named 'MadDog.png'. When this user now uploads, that watermark will be used for his pictures. Pictures uploaded by other users will get the standard watremark. To remove special watermarks for a certain user, just delete his watermark file.

Warning: when using the admin tools to change/ modify watermarks all special watermarks will get replaced with the standard watermark. If the logged in admin has a special watermark this will be used then.

here's the new picmgmt.inc.php

I have updated the new picmgmt.inc.php but it still isn't applying the watermark to the resized images on the resize only option.

[ edit | actually the new picmgmt.inc.php has made no difference ]

[Stramm]

tested again with only resized, only original, both and no watermark... works perfect. you really are using the actual version??
(I've used the version from the board to be sure it's the one it should be). In case it really doesn't work, attach your picmgm... and tell me something about your system

[Stramm]

When having a lot of pics the standard admin tools are a pain. On production boxes with a short timeout you only can process ~5 pics at a time. When done you have to click 'continue'. Doing that for a few thousand pics is annoying as hell. So here a lil hack for it.

What it does... the script simply calls itself over and over again till all images are processed. No need to click continue. Best is to set ~5 images to process at a time. If it really should time out with these only five pics just hit the browser reload button and it continues to work. So have a coffe and a lil bit of time and all's done by itself...

now place the attached file in your coppermine main dir

Have fun drinking your coffee

[Ancyru]

The picmgmt.inc.php is exactly the same as the one you just updated.

I forgot to mention that it's working fine on the files I just upload but it's not working in admin tools to update images.

[Stramm]

you should have mentioned that before

OK, either update 'function updatethumbs()' or apply the better admin tool hack for updating thumbs, normal and full images

if you stumble over some more bugs... you know where I am, hehehe

edit: I'm using the above mentioned hack... so I wasn't able to test the standard function. But the hack works smooth for me

[Ancyru]

Sweet, everything is working fine now!

    );

if (USER_IS_ADMIN) {
$form_array[] = array($lang_upload_php['disable_admin_watermark'], 'disable_admin_watermark', 5);
}


I've corrected this above as well

I get this error now:

Parse error: parse error, unexpected ',' in /home/staticp/public_html/photos/upload.php on line 923

this may be due to a mod that I have installed in that area...
here is what I have:

Code Select Expand

        // Declare an array containing the various upload form box definitions.
        $captionLabel = $lang_upload_php['description'];
        if ($CONFIG['show_bbcode_help']) {$captionLabel .= '<hr />'.$lang_bbcode_help;}
        $form_array = array(
        sprintf($lang_upload_php['max_fsize'], $CONFIG['max_upl_size']),
        array($lang_upload_php['album'], 'album', 2),
        array('MAX_FILE_SIZE', $max_file_size, 4),
        array($lang_upload_php['picture'], 'userpicture', 1, 1),
        array($lang_upload_php['pic_title'], 'title', 0, 255, 1),
        array($captionLabel, 'caption', 3, $CONFIG['max_img_desc_length']),
        array($lang_upload_php['keywords'], 'keywords', 0, 255, 1));
        array('event', 'picture', 4),                                                        <----------------- line 923

if (USER_IS_ADMIN) {
$form_array[] = array($lang_upload_php['disable_admin_watermark'], 'disable_admin_watermark', 5);
}

        );


sorry for all the trouble 

also...I have noticed that sometimes the quality of the original image is crummy (it appears that the normal sized version has just been stretched out and then watermarked at a larger size)...this doesn't always happens, so I don't know if it is because of server load or what...


thanks

Code Select Expand

array($lang_upload_php['keywords'], 'keywords', 0, 255, 1));
to

Code Select Expand

array($lang_upload_php['keywords'], 'keywords', 0, 255, 1),

with the ); at the end you're closing the array definition but continue in the next line with it
then as it looks that will just correct the error message you have now. Another one will show up.

The code should read...

}



the pic quality stuff that sometimes happens. It's the downside of having to recompress the images. Hasn't to do anything with the load. But if you want you can email me a pic (original for sure) and I'll have a look

But I really can't give you support with other mods
The above stuff's just obvious

cool 

that fixed the problem....thanks

on the image problem it seems to not be a problem in small batches...so for now I will use the util to fix the quality issues...but if you still want to see the image quality probs, I can post up examples for you...


on your util.php mod I get this error when I try to process the images:

Parse error: parse error, unexpected $ in /home/staticp/public_html/photos/updatethumbs.php on line 160

it seems the image quality issue isn't as predictable as I thought....I just did a batch of over 100 images, and they all seemed to turn out fine...but when I went through using util.php to try to fix the issues on another batch that had the image degredation, nothing happened...

here are two pics showing the problem I am encountering:
