To the balless bastard that negged me with:
Why don't we just make the VCR illegal while were at it 'eh? The .net needs to be free and accessable not copywriten for stupid commie. idiots

First of all, people take a lot of time to make some of the images you see on the internet, it takes more than just skill...it takes creativity and patience, and for someone to completely rip you off and claim it as their own is wrong. Protecting your images has nothing to do with communism. There are plenty of free graphic sites from which great artists contribute their work, it's when they have work that want to be protected and get called communists for that there's something seriously wrong.

I posted in another thread in this same forum that digimarc is probably your best bet, besides deterring from javascript and image overlays. A person CAN take a screenshot, but the watermark can still be read from the screenshot as can be with a deviation, depending on how strong the original watermark was embedded.
