Key Concepts
- Simple images should be described briefly or designated as decorative images.
- Complex images (e.g., data charts, infographics, maps) should be described elsewhere in the document; ALT Text should direct the user to a long description.
- Images that present no content or context may be marked as decorative.
Check ALT Text
For each web page or view:
- Activate the Check Images bookmarklet on the browser’s Bookmarks toolbar.
- Review the ALT Text overlay for each image in the page or view.
- Determine whether the ALT Text is suitable for the image:
- Are there images of text?
- Does the ALT Text provide an accurate and concise description of the image?
- If the images is a hyperlink or button, does the ALT Text indicate its destination or purpose?
- If the image requires an in-depth explanation, does the ALT Text direct the user to that information?
- If the images is purely decorative, does the ALT Text overlay read “Role='presentation'”?
Escalate for Remediation
- Informational images with no ALT text
- Images with inaccurate ALT text
