Noooo! Not the giant piece of code boated crap! I'll find you something, just give me some time.
Wait, is this for a personal site or a multi-user site?
Ok, there is...
http://thefilebrowser.com/ - great and super light weight if you can sacrifice d/l tracking and such...
http://gallery.menalto.com/ - never used it myself, but it's more light weight than copper mine, and has a solid feature set.
http://www.pixelpost.org/ - light and fast, smaller feature set.
I'll update this thread as I find more galleries that are useful.
