Just a random minor suggestion
Have you ever considered using another gallery app?
Such as "Gallery", version 3 beta has been released
I have my own gallery hidden on my server, right now its just more of a personal gallery of my favorites from the site

(Obviously im not talking about you using mine, but if you ever wanted to consider installing it on your server)
All I will say for right now is that soon, we won't be needing a gallery. There's going to be a upgrade soon and as soon as I iron out a few things, I'll make an announcement to that affect.
Awesomeness! any speak peak at what your upgrading to? :)
