Making client-side image maps accessible
Client-side image maps are preferred over server-side image maps for the following reasons:
- Alt attributes can be provided for each active region of a client-side image. This is not possible server-side maps, only a single alt attribute can be provided.
- Navigation through image hot-spots is possible using the keyboard with client-side images, but not with server-side image maps.
