Server-side image maps don't provide adequate support for alternative text as you can't provide it for each active region. Alternative text only applies to the map as a whole. This means that you can't access any of the links on server-side image maps on non-graphic web browsers or if images are disabled on a graphic browser. Also, server-side image maps rely on point and click interaction with a mouse, making them unusable by keyboard only navigation, i.e. for users of laptops without a mouse, screen readers, touch screens or special pointing devices. |
