Resources for Teaching and Learning

Allows users to collaboratively create and share diagrams. It is free to use

Has a collection of free and inexpensive images.

Google's image repository. They can be sorted by resolution and fair use.

Allows instructors to create albums by course or subject that students can contribute to and share

This is a site that has an extensive digital collection. You only have to pay for images that you actually want to reproduce.

There are free photos for use in your projects; some request that you give the photographer credit, or to let them know how you used their shots. Others don't even ask for that much. Cautions: The search function isn't great, and the selection can be limited in some areas. But there is a surprising amount of great free content. It's worth seeing if they have what you need.
