What Are Imagemaps?

If you use a graphical browser, you have probably noticed that many major Web sites have a large clickable image on their main page. These images are different from your run-of-the-mill hyperlinked graphic in that your browser loads a different document, depending on where you click. The image is somehow "multilinked" and can take you to a number of places. Such a multilinked image is called an imagemap.

The challenge in preparing an imagemap is defining which parts of the image are linked to which URLs. Linked regions in an imagemap are called hot regions, and each hot region is associated with the URL of the document that is to be loaded when the hot region is clicked. After you decide the hot regions and their associated URLs, you need to determine whether the Web server or the Web client will make the "decision" about which document to load, based on the user's click. This choice is the difference between server-side and client-side imagemaps. Either approach is easy to implement after you know how to define the hot regions.
