Add Alt-Text to an Image

There is a known and reported issue related to storing alternative text in Canvas so that it carries over when content is copied between courses. While there are multiple ways to add alt-text in Canvas, this page will cover the best way to add alt-text, so it is retained in Canvas.

Alt-text added through ALLY in Canvas Files or through the ALLY Course Accessibility Report will not be stored by Canvas and likely won’t carry over if copied or shared between courses.
