Please make sure your students always use copyright free images,videos and music when they're posting their work online.Just because a photo is in Google Images doesn't mean it's free to use. When searching Google Images, set the usage rights to "labeled for reuse."
Click on one of the links below to see websites that offer free images. Even if an image is free, a credit line may still be required. For example, the Department of Agriculture provides free images and requests they receive credit if any are used. An example of an appropriate credit line is "Photo courtesy of USDA Agricultural Research Service."
