Introduction
This module will focus on testing client-side image maps.
The Section 508 requirement that covers this is: §1194.22 (f) Client-side image maps shall be provided instead of server-side image maps except where the regions cannot be defined with an available geometric shape.
There are two kinds of image maps: client-side and server-side. Client-side image maps are the most common type of image. Server-side image maps are inherently inaccessible and should be avoided. Testing server-side image maps is discussed in a separate module.
The image map is called client-side because the browser (the client) processes selections or clicks on the map. If the selection falls within a defined <area> tag on the client-side image map, the client opens the corresponding URL associated with that <area> tag.
Remember, both testers and developers can use the checkpoints for this requirement to be sure the products they are working with will be accessible to users of Assistive Technology (AT).
Use the link above to look at the checkpoints now. You may wish to keep the window open as a reference to use as you complete this module.
Video Overview of this Requirement
To view an approximately two-minute video with additional information which may be helpful to testers and developers, select the video link below. This same video supports both the Server-side and Client-side Image Map modules and may be reached from both modules. The video will open in a new window; if you are using a screen reader to take this training, press enter when you hear, "To start, press Play button."
