This site has a small and high quality free stock photo collection with close to 300 photos. Smaller sites may offer viewer photos, but they often have photos of objects, people and places you won't find anywhere else for free. The terms of service clearly explain how you can use these photos.

Photo Repository has nine albums, which have photos relating to nature, food, life forms, textures, recreation, objects, buildings, landscapes and signs. Discover photos by exploring the latest uploads, most recently commented photos, most viewed, top rated, favorites and random.
