Built to offer free images to 3d gamers/3d modelrs /artist/ grandmas...whoever.
Eventually i also want to sell itmes of it like tiled image/web comics/art.

If anyone feels like it, i'd appreciate a review on:
1.general (I think I need to display that they are "free" somewhere on the main page. not too clear right now)
2.adsense, is it worth it. Can you actually make money off it or just enough for a weekend pizza.
3.add a menu. took it off and will replace it a couple of search boxes on the left hand column. Opinions on that?
4.a login to better control possible download issues.
5.anything else. feel free to say.

thank you
