How do I get permission to use CK-12’s images?

To use an image from a FlexBook® textbook, please first check the source and license information for that particular image. If the source is listed as CK-12 Foundation, you have permission to use the image under the CC-BY-NC-SA license. Details about your CC-BY-NC-SA license can be found here.
