It works so well that i have to write it again: good job!
Now some things I would change/add if I could:
1) "Total number of photos on page" in gallery (default) settings
2) FANCYBOX frame modifications. This white thick one is not the best one
.
3) More photo management options, like: compression, size, etc
4) "Disable SAVE GRAPHIC AS ..." option
5) Few more hover effects
6) LOAD MORE button customization.
Well... All of above are just tiny things. I thing OS Gallery is the best choice. Simple, effective, easy-managable, pretty.
