Often instructors are looking for images to use in their courses because images can liven up the course and help students understand the course material.
A picture is worth a thousand words, but it might also be worth a thousand dollars if your school gets hit with a copyright violation claim. —Eric Curts
There are many high quality pictures that can be used without any licensing concerns. These can include images that are released under creative commons, or are in the public domain, or simply are copyright-free.
Eric Curts compiled a list of free image sites and tools for schools that you may find helpful in your search for free images.
Two sites I use often that didn't make Curt's list are Creative Commons (CC) Search and the Noun Project.
Are you looking for images of diverse people? This curated list of image collections featuring diverse people by Online Network of Educators may be of interest to you.
Images have the power to enhance your message or story, they can also become a big distraction when used improperly. Check out this Mistakes to Avoid When Using Photos in eLearning blog post for some common mistakes.
Additionally, you may find an image you want to use, but you would like to make changes to it. You can find free photo and image editing tools in this eLearning Industry blog post by Christopher Pappas. Just make sure the image copyright gives you permission to modify the image.
