When I'm looking for inspiration, or I want to see what kinds of images other people associate with particular concepts, I often search flickr. Now Ryan Teuscher and Bryan Denman have made that easier with compfight, a flickr search bar.

compfight, which its creators say was put together with "with glue sticks and rubber bands," can filter images on several criteria; for example, it can limit the search to images licensed by Creative Commons.

Like flickr, compfight is free.
