The Creative Commons search tool allows access to over 300 million openly licensed and public domain works that can be used by everyone.
You can quickly search through the Creative Commons media for images and sounds to include in your Mission. It’s really easy! If you have not added an image or sound already, just click “Search Commons”. Then, enter keywords for whatever you are looking for into the Search Keyword(s) field and pick an image or sound from the list. Attributions for the content will automatically fill out for you when an image is chosen.
