Ways to Find Random Pictures

Granted, I'm not a photographer but I admire people who are. When you first go to the Creative Commons the search box has the words "Enter Search Query" in the box. Of course you are supposed to take this out and well enter your search query. However, if you click on it before you'll come up with pictures from people who have tagged their photos with "random search query". A very clever way to get more hits and viewers.
