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. :)

nice work, I'll try it out now ^^

Logikos

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.

Great hack - really enjoyed it!

Very cool, However it is not working in 3.0.1

This is what I have at the end of my attachment.php

echo $attachmentinfo["$imagetype"];
}

Any ideas on how to get this working with 3.0.1?

Thanks,
Miguel

what does watermarking do?

It brands your images with your site name or whatever.

it is not showing up .. the watermark.PNG .. also the load of an image as attachment ist now ultra long .. depnediung 10 or 20 seconds till the images loads when i cklick on a thumbnail ..

*going to remove it till its working or anyone knows why its not showing up ..

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

heh, I'm on broadband and that was still slow.

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

Robbban

08-11-2004 04:14 PM

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

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

Does this work for attachments stored in a filesystem?

This hack works for non-marked images. I will soon release a modification that will watermark images as they are being uploaded. I'm also thinking of a script that adds a text-file to ZIP/RAR/TAR/GZ archives so you can "watermark" those aswell!

I'll bet you *do* have a file by that name.

It's in the folder that conatins all the functions files, its name is includes/ .
