The watermark should be able to be either text or an image, configurable in the ACP if possible. Also the location of the watermark would be nice to select, for instance Top-Left, Top-Center, Top-Right, Dead-Center, Bottom-Left, etc.
I got the idea from a Mod for the Smartor Album-software which works on phpbb2.
Perhaps something like this would be easier (?) to do if all uploaded attachments where first resized to a max. certain amount of pics perhaps, like 1024px or 800px wide?
