The page includes a server-side image map. Verify that the image map can be replaced by a more accessible client-side image map.

Determine whether the server-side image map is really needed. The only reason to use one is if you need to define active regions that cannot be defined with available shapes. If you must use one, you should at least provide alternative ways such as textual links to reach the same destination pages. (You must inspect the implementation of the image map on the server to find out how active regions are defined.)

Server-side image maps pose big accessibility problems, including:

• Server-side image maps require specific input devices like the mouse, which may not be available to certain users in certain contexts (such as users of cellular phones or voice controlled browsers)
• Certain users in certain situations may not be able to accurately click on the map (such as disabled persons or persons walking, driving, or standing)
• The links specified by server-side image maps are hidden in the server and cannot be manipulated by browsers in any way, including any assistive technology. Therefore, the browser cannot communicate any alternative links to the user
• Server-side image maps are less efficient than their client-side counterparts because an additional interaction with the server is needed for each user click

For these reasons, the use of server-side image maps is highly discouraged. The only exception is for active regions whose shape are so irregular that client-side image maps cannot support them.

You can recognize a server-side image map with a browser by pointing the mouse at the image. Mouse coordinates are displayed by the browser as you move the mouse over the image.
