I love Wikipedia.  But even better, this wiki encyclopedia has added a section called Wikimedia Commons.  Wikimedia Commons “is a project that provides a central repository for free images, music, sound & video clips and, possibly, texts and spoken texts, used in pages of any Wikimedia project.” Anybody can go there and upload their images to be used in Wikipedia entries–you should browse what’s already there.  And, Devon, you should upload a bunch of your images.
