This is is going to be the start of a list of useful links to various sites where you can get textures or sprite images. If anyone adds some gems, then they will be added to this post, so people don't have to go through every post.

NOTE: Many of these linked sites have not been checked for what contents they offer.
If they don't appear to be what is advertised, or look suspicious. Then PM an administrator so they can be removed.
So use at your own risk.
