At first, I had to giggle when I read about this, because, being strictly a hobbyist, the thought of anyone paying actual MONEY for anything I have created never even occurred to me. Then I realized that many people who post here are actually professional artists and this has to scare the **** out of them. But, if someone steals an image of a Bryce pic you created and tries to pass it off as theirs, surely the fact that you have the original Bryce format file on your computer would prove beyond a doubt that you are the artist. Does that makes sense?
