It requires a working knowledge of HTML code, available CGI programs, and the capabilities of your Web server. Making a client-side image map work is relatively easy. Client-side image maps, however, only work in newer browsers, such as Netscape Navigator 3.0 and Internet Explorer 3.0. You also might consider using several individual images as links instead of an image map. To create either kind of image map, you need to assign hotspots to the image.
Hotspots are areas on an image map that viewers can click to open different URLs.
Choose the Edit button next to Client-Side Image Map. The image file opens in the Client-Side Image Map Editor. Select the Rectangular Link or the Circular Link tool in the Client- Side Image Map Editor toolbar and draw a rectangle or circle over the area of the image that you want to be a hotspot. When you are finished creating the hotspot, the Link Editor appears. Type the filename or URL of the link destination in the URL text box.
