WHAT IS AN IMAGE MAP?
Earlier in this
lesson, you learned how to create an image that doubles as a link simply by
including the <img> tag inside a link tag (<a>). In this way, the
entire image becomes a link.
In an image map
different parts of the image are different links. You can specify that car – train
areas of amp link to various pages, as in figure.7.17. Or you can crate visual
metaphors for the information You’re presenting, such as s set of books on a
shelf or aa photograph with a link from each person in the picture to a page
with his or her biography on it.

DIFFRENT LINKS.
There are two
kinds of image maps: server- side image maps and client – side image maps.
Server-side image maps were used in the earlier days of the web, but they posed
some problems for web authors, and have fallen into disuse. In this lesson,
client – side imagoes, which are handled completely by the browser, are used
almost exclusively and offer man you advantages over older, server- side image
maps.
