Tell Me

This issue is caused when an image is added with the “Insert Content” tabbed panel, or when an image is added with the “Embed Image” Button in the Rich Content Editor and there isn’t a brief description (100 characters or less) of the image contents entered into the alt text field. If images don’t have alt text, then students who rely on text-to-speech or screen reader programs to view the web will not be informed that the images even exist. Simultaneously, if the images do not have alt text and become disabled, a sighted person will not be able to figure out what the purpose or subject of the image was.

  1. Click the “U FIX IT!” button.
  2. You will be provided with a new alt text field where you can enter an up to 100-characters long description. If the image is intended to be ‘decorative’ instead of ‘informative’ to the learning process, mark the “decorative” box. Once your description is written, or you’ve selected the decorative box, click the “Submit” button.

False Positives

If an image is purely decorative, meaning that the image is not significant enough that students will mention the image in conversation or use the image as a reference point for finding other information on the page, then leaving the Alt text field blank or creating null alt text (alt="") is a perfectly accessible practice. Examples of such images include borders at the beginning and end of each page.

It is because null alt text can be used in an accessible way that the Accessibility Checker (UDOIT) ranks this result as a suggestion instead of an error. However, you should treat this result as an error 95% of the time.
