I forgot to mention this earlier but I've started to pack up and release a bunch of backgrounds and things that I've decided I ultimately won't use for anything and even some things that were used in small projects. They're mostly backgrounds, and I'll probably keep this up and release more at some point. As many of you know I'm definitely not the best artist around here, but I think that they're some solid beginnings of rooms. Feel free to edit them or whatever you feel like doing with them.

It's kind of dead, but perhaps also posting your files here (http://www.adventuregamestudio.co.uk/yabb/index.php?topic=14864.0), may be of some use. Regardless nice move, Schmaig :P
Dunno if you're doing this already, but http://www.opengameart.org/ could also do with more stuff!
