Hello, I believe the subject of how to maintain the security of images placed on the WWW has come up on this list before, but I can't remember when. I'm looking for any information on how to prevent or deter misuse of artifact images placed on the WWW. I'd be very grateful if someone could point me in the right direction. Thanks for any help!
