Using the Accessibility Checker to fix Alt Text and Heading Errors

Adding Alt Text to Images

When the accessibility checker alerts you to images without alt text, follow these steps to add alt text or mark the image as decorative:

  1. Right-click Figures alternative text - Failed.
  2. Select Fix from the context menu.
  3. Add alternative text to the text field.
  4. If you have multiple images, click the next arrow to continue adding alt text to images in the document.
  5. If the image is purely decorative, select the Decorative figure checkbox.
  6. Once you add alt text to your images, save the document and run the accessibility checker again to ensure all images are fixed.
