Don't sweat it.
Sometimes it just takes longer to have a picture or gallery approved, that's all. There has probably just been alot of uploads lately or something.
I remember when fixing around with my Brickshelf a while back, it took about 2 weeks for them to approve my minifigs gallery, but it turned out fine in the end.
If there are alot of pictures in a folder, I think this lengthens the approval process, since there are more images to check. If they didn't like something about your photos, they would just delete them.
Avast! You've beaten me to the punch, Thomas!
