Your program looks good, leaps and bounds ahead of where most "indie" sites are at program launch. I've signed up, and you have a PM.
The only thing I noticed that you'll want to address right away are the empty titles on your hosted galleries. They're important for two reasons. One, search engine optimization, not that you'll get a huge amount SE traffic from your hosted galleries but every bit helps. And two, the title text is what appears in the Bookmarks/Favorites when someone saves the page to view later.
