This hack adds a watermark to attached images. The watermark, as specified by your own .png image, is added on image download, not when the image is attached. Requires GD2. Do not even try installing if you don't have GD2.

Grrr... I have GD2 but still after installing this all my attatchments show up as little X's...

Could it be that my .png file wasn't the right type?

Awesome job filb! This should help with preventing people from hotlinking attachments (not that I think they can anyway, since .htaccess things I've applied).

To my understanding, everytime the image is downloaded (viewed), you will get a watermark picture.I think (but don't quote me) it works for hotlinking as well as yoursite.

Anyway, how do you know if GD2 is enabled? Is there an easy way to find out? (I don't really know all the server details, I don't own the site/forum or anything.) Hopefully it's located somewhere on the site...

I found out by simply emailing my host and confirming it that way...

Email=good

Anyway, speaking of that I am using 2.2.9 and the code in attatchment.php is very similar.. Is that the reason this doesn't work for me? Has anyone else tried this in 2.2.9? What should I do? This is one of the coolest ideas ever and I can't use it

GIF support in PHP is generally horrible. However, I have a solution (which I don't have time to implement but anyone with GD2 experience can):

1. Load the gif using imagecreatefromstring
2. Create a new image via imagecreatetruecolor of the same dimensions
3. Copy the entire gif onto the new image
4. Destroy the original gif

The problem is likely a palette issue.
