Images & Alternative Text

These guides and videos provide steps to help you make your image content accessible through the creation of relevant, comprehensive, and succinct alternative text (alt-text) and long text description. For the best accessibility practices around authoring alt-text, please check out our MSU Denver Alternative Text - The Basics Guide.

To learn more join us for our Authoring Awesome Alt-Text Workshop. Our Schedule can be found on our Events and Workshops area. 

If you have a question that is not answering through the content below, please contact the Instructional Accessibility Group via email at: InstructionalAccessibility@msudenver.edu


Option 1:

In Canvas, the file name is the default ALT text which is usually inaccessible, but if you change the file name to the ALT text, it will always be inserted when the image is placed into Canvas content. This first option should be used for images you will not use more than once (repeating images generally means you will need to adjust the Alt-Text to reflect the shifting context)

  1. Upload your image into the Files area of your Canvas course; navigate to File to complete the rest of the steps.
  2. Rename to match your default ALT text.
    1. Hover over your file
    2. Click the three dots at the right end of the file line
    3. Click Rename
    4. Type the new name
    5. Click the check mark to save.

Option 2:

Add or Edit ALT Text in Rich Content Editor. This option is best for images whose Alt-Text needs to be adjusted for the nuanced contexts of a course/module.

  1. Open the Canvas Rich Text Editor to content which includes an image.
    1. This could be under pages
  2. Click on an image added to content to highlight it.
  3. Click Options at the top of the image to open a context window to the right.
  4. Type the Alt-Text in the box under “Alt-Text”
  5. Click Done
