Free Picture Web Sites
Below is a list of absolutely free picture websites! Some of the photos and pictures are in the Public Domain, but many are not, so make sure to include a source (the web address for the image) for each picture or photo you use. That way, we can practice good Internet etiquette and give people credit for taking the photos.
Can't find the picture you want on one of those sites. Use Wikipedia to find images, but make sure that you give credit and provide the source.
