IMHO its because it wasn't one person posting pictures at the time you closed it. There were several regular contributors at that time, even if there had been points when it was only @wtw. Also, probably because you were/are the only mod to noticeably take an issue with it. And given that @CalBear had actioned a user but not closed it the thread it did seem a bit like you were jumping on an excuse to close a thread you didn't like. And since you asked for a Help and Rules thread about it here we are.
