http://www.everystockphoto.com, another "free" stock image website.
This one has a twist. It's partnering with Fotolia and shows their paid images in a column to the right. Might be an interesting approach. There are an increasing number of infringement incidents with Creative Commons and commerical usage. The Virgin/Flickr incident for example. I wonder what affect this will have on leading skittish buyers toward buying a properly licensed commerical image.
Dan Heller has several great thought provoking entries on his blog about Creative Commons.
