The watermarking works great, but images are indeed loading much slower than they used to.

Here's an example of the watermarking for those requesting for one: http://www.pdatrends.com/attachment....tachmentid=676

I will definitley call this a great hack but the loading problem keeps this hack from becoming a clasic.

Hmm, yes... I noticed that the "on-the-fly" watermarking isn't good for performance. Going to modify this and release a version that watermarks the uploaded image so the script doesn't have to watermark every image everytime someone requests it.

It will probably be release tonight (in 5h) :D

For you with problems, here are something to notice:

* It's been tested and developed for version 3.0.3
* watermark.PNG and watermark.png is two diffrent filenames. On unixsystem watermark.PNG will NOT work.
* Live demo can be seen at *WARNING, ADULT SITE* www.synd.nu

Thanks,

This is a cool hack works well but for it to work on 3.0.0 and by the look of it 3.0.1 you will need to use this code.

find:

Code:

echo $attachmentinfo["$imagetype"];

And replace it with:

Code:

        if (strpos($attachmentinfo['mimetype'],"image/jp")) { $isjpg = 1; }

        if ($isjpg && !$_GET['thumb']) {

            $filename = "/home/your/path/watermark.png"; // use a PNG-24 to preserve transparency!



            $im = imagecreatefromstring($attachmentinfo['filedata']);

            imagealphablending($im, true);



            $watermark = imagecreatefrompng($filename);



            $y = imagesy($im) - imagesy($watermark);



            $w = imagesx($watermark);

            $h = imagesy($watermark);

        

            imagecopy($im, $watermark, 0, $y, 0, 0, $w, $h);



            imagejpeg($im, "", 80);

        } else {

                echo $attachmentinfo["$imagetype"];

        }

Remembering to change your /home/your/path/watermark.png
