Quote - "how would you feel if you found out that someone who stole your images was making prints and selling them for profit in street markets?"

Well, I guess I would have a mixture of emotions. I guess I would a) feel proud that someone would actually buy my images, b) feel stupid because I didnt have that idea in the first place, c) feel good because I was helping some poor guy to make some money.

Something completely different would be if I found that some rock band, for example, used one of my images as a CD cover without my permission. Then I would try to make some money out of it. :-)

But none of these experiences would make me feel any different towards watermarking. I wouldnt start doing it because, after all, none of these experiences would damage me in a concrete way nor would they decrease the pleasure that I take out of creating images (maybe even the contrary is true).
