Image: The image does not have a description

  • Issue Category: Major

Tips on How to Fix Image Description(s):

Close-up of red indicator with file name and 25% score

If your image lacks a text description, the Ally indicator will appear “red.” Selecting the indicator will reveal that the file is only 25% accessible because it lacks an alternative description. Click the “What this means” button for an explanation, and “How to write a good description” for some quick tips.

Close-up of text box to add an alternative description for an image

When you’re ready, simply add your alternative description to the text field in the Ally feedback window. You can also edit existing text in the box. When you’re done, select “Add.” Make sure your description is more than just the title of the file, or Ally will report an accessibility error. Describe the image and what’s important, and mention any text in the image to improve your score.

Close-up of Decorative Images description and button

If your image is only for visual affect, and does not contain info relevant to the learning content, you can also mark the image as “decorative.” This means no alternative description is necessary, and your accessibility score will improve. This helps assure students of the purpose of those files.
