My point about permission didn't reference copyright law. What I'm saying that just because a person doesn't mind if someone grabs their image, this doesn't make those who then take that image immune to violating copyright, in the same way as the theft of an object is no less theft just because the owner doesn't want it any more. They have to explicity make this known, hence written permission, which is the only feasible solution when dealing with web copyright. And yes, if it's written in a thread then of course that's OK. I never said otherwise. "Therefore, if someone is using a copyrighted work to educate themselves without profitting from the act, it is viable Fair Use according to the law." lol! I know that. But are you trying to tell me that people are downloading images in order to educate themselves about artwork! I wouldn't like to tell that to the judge! :D
