I often find myself looking for free images for use in a project. It can be hard to find quality stock photography for free. Today I came across a site though that has really made my day, MorgueFile. (Sound weird? They explain the name on the home page).
Unlike some other sites where a search for a hum-drum term like "documents" returns 30 pictures of a kitten off of Flickr, this site has a good stock of photos, and a good search engine. The site also provides a lightbox (store photos for future use). Check it out!
