Are there any others that you know of and like? By all means, please let me know! I'll add them to the list and it could help everyone out!

If you have any resources you'd like us to add, just post them below!

There's also...

http://www.posemaniacs.com — The poses may be a little stiff, if you ask me, but if you're doing a quick sketch or warm-up, it's a good place to go.

and then there's...

http://www.mayang.com/textures/ — All sorts of textures here for your work! But they're great for references, too (ex: landscapes, stonework, whatever). Keep in mind that there IS a download limit per day!

I'll come back when I remember more.

Those are excellent! thank you so much!
I love how you can rotate the figures on that one; it's a pretty damn useful feature.

Thanks, Saphine for those links! I was actually trying to find posemaniacs after my bookmark disappeared into the abyss of my pc.

Gah, I need to add these:
http://step-in-time-stock.deviantart.com/gallery/ -I LOVE this one, I really want to use the hell out of it.

Also, using these now as well:
http://stock-directory.deviantart.com/
http://pose-emporium.deviantart.com/

Have my three cents, I love collecting art resources!
