Rule Description

The document contains an image map that is server-side instead of client-side.

The Algorithm, in Simple Terms

Ensures that server-side image maps are never used.

Why this is Important

Server-side image maps are not keyboard accessible; mouse clicks are required to access the links contained in the image, making the image inaccessible to people who only use keyboards for their navigation.

How to Fix the Problem

Change all server-side image maps to client-side image maps.
