Hi Rustyhands
I have heard lots of stories about photos being misused on the world wide web, and I know of people who have openly admitted they have taken other peoples images, and made them their own. I have heard of other people have found out the hard way, that someone has been using their photos and making them their own regardless to their cost.
Personally, I think anyone who steals another persons photo of any website to get a result is out of order.
I agree with Mightypain that if you have very valuable photos that you simply do not post them at all.
Watermarks vary in that you can post a shadow mark through your photo, or place your signature. I think a signature on the corner of your photos would be a great idea for peace of mind for yourself and it had not got a detremental {sp) effect on your prized photo
Regards
Kathy
