Thanks to Sacha Chua (in her own words a enterprise 2.0 consultant, storyteller, geek, and more) I stumbled upon compfight which searches through Flickr for CC (CreativeCommons) pics.

Like Sacha I like the layout of the results page and they seem to fit in a lot more pictures than Flickr:

You can limit the search to include only CC images as well as images that are “safe” – which is always a handy feature.
