Photo Web Site

Almost everyone who works with me knows of my intense dislike of clipart. (I should clarify, it is the "standard" clipart I dislike, and how it is generally used in course and other learning materials). So I am always on the look out for good photo sites. I recently came across this site: http://everystockphoto.com/ and am really enjoying it. It links to free photos (doubel check the lisence agreements just in case) and searchs several sites including Flickr.
