Good websites for photos of models posing

Hi all

As someone who can't draw, I use reference images from photographs in illustrator to manually trace around (I don't mean the trace feature or pathfinder etc) - I mean just have a low opacity photo in the background and use that to draw semi-realistic but still cartoonish characters based on the photo.

Anyway, it's easy to find single pictures of people's faces, but I wondered if there was a good website which showed the same people in different poses, especially head profiles - Several pictures of the same people with different head movements (looking left and right) - and preferably full body photos of them in either A-poses or T-poses. (Photo's - not 3D models)

If anyone knows of any good sites which provide these types of images (I've been trying Google forever, I can't seem to find anything relevant to what I'm looking for).

I guess that people use these types of reference images for 3D work as well as 2D, so I'd have thought the internet would be full of sites like this. Maybe I'm using the wrong search terms.

Anyway, any suggestions would be greatly appreciated.

Thanks in advance.
