I looked into bigfoto.com and found pictures from around the world. They have categories which enables you to quickly find pictures in a certain theme. Most of their photos are from amateur photographers. Their copyright is very simple. You have free use of all pictures if you provide a link to their website.
Freedigitalphotos.net is another site on the web to download free photos for use in corporate and personal projects. You can browse by category or search for exactly what you need. The photographer and freedigitalphotos.net must be acknowledged; however, if you purchase a photo, there is no requirement to place a hyperlink. Images cannot be offered for sale, claimed as your own work, or included in web templates for mass distribution.
Flicker.com has my vote as the favorite search engine for photos. Their free site is user friendly with an abundance of images and good tags. You can also upload your own photos to share and edit.
I searched schoolsclipart.com and found an image that we could use on a poster promoting a young adult bookclub at the library.
