Section 508 Web Standards
(e) Redundant text links shall be provided for each active region of a server-side image map.
What does it mean?
The image map uses images that act as links (hot spots) when they are clicked; however, people with visual disabilities do not know where the links are. The server decides where in the image the person actually clicked. Putting in text links next to the map allows screen readers to identify and choose the links. These images have text equivalents that provide the necessary information about the links.
How to evaluate
There are text links before or next to the image map and the assistive technology device such as a screen reader can find them. The image has an Alt attribute with an explanation of the text links. All images on the map are represented with text descriptions that provide essential information. (Note: Most web developers are working with client-side image maps instead of server-side image maps.)
