WebworkClient-Side Image Maps

An image map is a combination of an image with a bit of HTML coding that designates certain parts of the image as "clickable" hypertext links.

The coordinates for the above Treasure Map look like this:

<map name="treasure-map">
<area shape="rect" coords="97,75,142,106" href="www.geosociety.org/">
<area shape="rect" coords="48,38,87,76" href="http://www.palms.org/">
<area shape="rect" coords="120,17,155,50" href="http://www.thex-files.com/">

The image tag for a client-side image map would look like this:

<img usemap="#treasure-map" src="images/map.gif" width="189" height="155" border="0" alt="treasure map">


To create the list of coordinates for making image maps an application like Adobe ImageReady or Marcomedia Fireworks is helpful. These apps allow you to load an image and view it while drawing shapes on it that determine what areas will be clickable links.
