Themeless galleries aren't all that useful or attractive unless you've got some kind of sorting or naming in place. At the very least place them in order of artist so it's obvious who drew what picture.

Sorry for the loss. I lost a 4+ year Imgur account when I accidentally privately uploaded some images of celebs (Phoebe Cates, Natasha Kinski, Terri Nunn) from mainstream films/publications without first checking on VEF if their "early work" was legit.
Anyone know a decent image hosting site that does NOT suck?
