More cleaning and changes with no real affect

* Moved "injection" script to the bottom where it's out of the way.
* Another missing semicolon. (Damn it <_<)
* Cleaned up variable declarations where already declared, used more often than needed, or not declared at all.

Planning on doing something about the paginator from issue #1 and adding in a new option that might help out users that prefer to load full size images first.
