File organization? Options

[Maccabee]

I like keeping my computer organized but it has gone a little out of control.
I organized my photos but have yet to organize my documents.
But mainly I want to know how you organize your photos? Cause I have a folder for gimp "creations" and I always keep the editable file as well as a png right next to eachother.
But eventually this will get out of hand.
I realize this thread cant get to much depth but I appreciate your help.

A clean freak,

I even boil my organization down to subjects.

Creations >> Icons >> Heroes ; Gossip Girl ; LOST ; Misc
There are more too, those are just the only ones I can think of without looking at it.

I'm not too OCD. It just makes finding things easier.
