So the good pic I put up is ignored and eventually deleted, but the one I don't want up, and the one that's actually gotten a friend of mine in a little trouble, no less, gets (apparently) approved so people can point and laugh at it more.
The only reason it wasn't deleted after three days is because it was flagged, which resets the three-day clock. Which is just another reason why unapproved images shouldn't be flagged.
