One of the main issues with reusing digital media is determining who the creator is and whether/if the creator has allowed content to be reused. Fortunately, there are several excellent, freely-available resources for finding images whose creators encourage reuse.
Flickr is a public photo-sharing site with billions of images. It is a rich resource to find images for your research (news events, places, people, etc.). Flickr users can opt to share their images with others under creative commons licenses (alternative to copyright).
Search Google Images and limit to .gov
Tip! Images produced by the federal government are in the public domain. You can use them without seeking permission. To be certain, check image rights statements.
