Image Maps
What do I need to do?
Use clear and informative alt text for each part of a client-side image map. Avoid the use of server-side image maps if possible.
How do I do this?
Client-side maps need to have a usemap and not ismap attribute. Each part of the image map should include alt text that is the same as the text contained in the image. If using a server-side map, provide redundant text links for each active region, explaining where to find these links in the alt text of the image.
Why is this important?
An image map is an image with multiple active regions, each of which takes the user to a different location. Client-side image maps allow for both mouse and keyboard navigation and function like a series of links for those using text-only browsers. Server-side image maps only allow for mouse navigation and should be avoided or supplemented by alternative links for each active region.
