An image map in XHTML or Web Development is an image that has different clickable elements within the same single image. This allows Web developers to define only portions of the image as clickable while others are not, or to define specific areas of the image to point to different URLs.
Pronunciation: im aj map

A client-side image map in XHTML would have the following code:
<img src="image" usemap="#map" />
<map name="map" id="map">
<area shape="rect" coords="0,10,20,40" href="URL" alt="click here" />
</map>
