Anyone knows how to apply steganography watermarks?

Hmm, if you apply it on your image directly, it will sorta damage. I suppose the reason you want it is so that you can prove people stole your image if the need arises?

If you want, there are many progs to save a special signature in the EXIF data..

Yah, but I guess steganography watermarks don't really do damage to the image itself... It is only the quality of the embedded image that is affected more...
