How can I add banner images in a customization course?
Add externally hosted images to the [Banner Images] page of your institution's Primary Customizations course.
To add custom banner images for use at your institution, go to the [Banner Images] page in the Primary Customizations course and follow the instructions on the page. You can also find more detailed instructions and tips on the Banner Images Instructions page of the DesignPLUS Admin Guide.

Note that any images you add to the [Banner Images] page should be housed on a secure server (https) outside of Canvas, to ensure that they can be loaded and viewed in any Canvas course. If you do not have easy access to external storage space, you are welcome to send the images to us by attaching them to an email addressed to support@cidilabs.com. We will upload and store the images for free and reply to your email with the public URLs so that you can add them to your [Banner Images] page in the customizations course.
