Ally: How to Add a Description to an Image in Canvas
Purpose: Image descriptions and alternative text are used to provide contextual information displayed in an image. This is particularly important when images are meant to provide information to the user. While alternative text and image descriptions can be used by anyone, they are necessary for individuals who rely on the use of screen readers, as that is the only way those individuals are able to receive the information in the image.
