harmy just posted this - I thought I'd share it here. I get a LOT of new artists asking me where to get copyright-free photos for references, of models, for poses, etc. etc. etc. If you're not lucky enough to have friends who send you photos, or are sick of doing self-portraits, you might want to go here:
They have a wide variety of free pictures for you to base paintings on, use as photo references, etc. with no strings attached! Thousands of different people, animals (even cats, hehe!), flowers, plants, buildings, facial features, etc.
