I thought I saw that before

Ditto.com ( http://www.ditto.com ) is an image search engine that allows you to both browse by category or search by keyword. They claim to have no pornography: ""Human filters" preview every picture ditto.com shows, eliminating objectionable material and applying editorial judgment to choose pictures that are most relevant and of the highest quality." This from http://www.ditto.com/Information/about_us.asp . If you're looking for an image but can't find it on their engine, you can make a request of the "Ditto Detective" and they'll search the Web for you.
