Ken, it seems to me the difference is that in the drawing you posed on the UK forum you claimed it was copyrighted, so the moderators took it off because they didn't want to get in trouble for posting copyrighted material w/o permission. The images that the OP posted do not say they are copyrighted. If every forum had to worry about taking off photos and images that are of something that is copyrighted, a lot couldn't be posted it seems to me. And surely it isn't the moderator's duty to look at every image, then think "hmmm, is this a copyrighted work," then if they think it is to take steps to find out. So it seems to me the difference is that one image said it was copyrighted and the other did not.
