You've always got some self appointed guru that has been named the grand poopah of the group. Browsing usenet newsgroups is not an activity that excercizes one's sense of frugality.
If I wanted to post a picture that had to do with the problem being discussed, I would post it and tell the guru to kiss my ass. If it helps some guy with a problem get it fixed, then that is the point of the newsgroup to start with.
