Image map is missing links and/or alt text
All actionable images (e.g., links, buttons, controls) MUST have alternative text. Server-side image maps SHOULD NOT be used when a client-side image map (or other method) can accomplish the same functionality.
Server-side image maps cannot be made keyboard accessible and screen reader accessible and are strongly discouraged. If a server-side image map must be used, alternative, accessible text links must be provided for each active region of the map as well as appropriate alternative text for the map.
Fix this issue by doing ALL of the following:
- Provide alternative text for the image map that directs screen reader users to the text links that provide an accessible alternative for the image map.
- Provide a redundant set of text links for each active region of the map so keyboard and screen reader users can access the links.
