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!

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

If that image is an indication of how images load.. I'll pass.

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)

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

Any ideas on how to get this working with 3.0.1?

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:

echo $attachmentinfo["$imagetype"];

And replace it with:

	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
