Know of any good resources? Post them here!
I use http://sweetandtalented.com/ for pictures of people. They dont have everybody, but they have a lot. I found the owner to be really nice if you were nice. I politely requested Paramore, and within three days she had them on her site! Overall, its great.
For textures, I use http://feel.hironeko.net/resources_textures.php
And you can often download gimp brushes from deviantart!
