Server side water marking

[kittytooth]

Im starting up a site that will allow clients to publish comics. Everything is is server side, even the image hosting. They can link into the image (and of course save it), but i am looking for a server side watermarking script that can be run in real time after the image is writen. Id like to stay in the pure dhtml range. Im not worried about people stealing the image, because there is not theft online (l33tness comment). I just want the watermark there for cold linkage purposes so i get more hits. Ideas or scripts please>? :confused:

you can't stay in the dhtml range and have it be server side...

it would be helpfull if you told us what server side you are using.
