Personally, (not that anyone asked or probably gives a fuck), I despise copyright laws and ignore them on a daily basis. Mostly this is because they are misused and abused by big business who makes a living out of crushing small business competition, unfairly exploiting artists/employees and milking the general public for all their worth. Copyright laws are outdated and insane.
That being said I have nothing against small businesses and your average joe needing some form of copyright laws to make a living and just make an honest yen. In this case I side with aquamarine. I don't think, however, that Neodoll is aware of exactly what picture is the offending picture. It was probably just in a folder he had and it was posted inadvertantly with no desire to offend anyone. You should probably specify the picture in question, (the bullet train, if I remember right?), so either NeoDoll or one of the moderators can remove it.
Pictures posted on the internet are generally considered up for grabs, (just ask our member RicX who has a photo site for his magazine scans but is one of, if not thee, most reposted person on the internet), so the possibilty that he grabbed it off a chan site or another imageboard is also highly likely.
Sry for inflicting my opinion on this but I was bored and thought my input might be useful. Maybe not.
