Howdy /c/ute /c/ompanions (ok, i admit, that was a little off).

Been hanging around /c/ for the past few days, slowly building up a collection of images. Already got 1303! Anywho, my question is this:
How do you keep your pictures organised? Currently have them sorted by character, however i can see the issues that will arise for pose threads, etc. I'd have to scout through the hordes of images.

Any good tagging systems/whatever?
