Users click on the hotspot to link to and display a different document , which can contain text or another graphic. You use image maps to define the hotspot areas.
Clickable images help illustrate a description of a product or explain a concept.
Different parts of an image map can each be a hotspot that links to different documents. You could also use clickable images to visually document a complex piece of equipment. The user could click on the various components and get an explanation, a more detailed image, or even a video and audio clip. A map file describes the clickable regions in an image and the links to which they point. You need to create a separate image map file for each clickable image on your Web server.
