Watermark images (on the fly)

This is something i made because I couldn't find any hack working for 3.0.7. Just took a couple of minutes. ;)

Works with 3.0.7!

I tested on my site and it seems nothing has happen. I replaced

PHP Code:


		
			
echo $attachmentinfo['filedata'];

With

PHP Code:


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

    if ($isjpg && !$_GET['thumb']) {

        $filename = "/home/vbhacks/public_html/forum/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['filedata'];

    }

And uploaded this in my forums directory. But nothing shows when i click on an attachment. Something im doing wrong?

Hmmm... Have you tried to reload the page with CTRL+F5? Internet Explorer caches all images :)

Edit:

watermark.png is one thing and watermark.PNG is another. Change the filename. :)

I tried what you said and still seems like nothing has happen. Will this only work on vb 3.0.3? cause im using 3.0.0 but the code seems there is no diffrence.
