Client-side Image Maps
Client-side image maps refer to HTML documents that contain the coordinate pairs and associated URLs embedded in the document sent to the user. They are faster and easier to setup. Unlike server-side maps, authors do not need to work with the web server administrator to setup client-side image maps. They are also faster, since all of the information for processing user clicks has already been delivered to the user.
Here is a MAP example:
<IMG SRC="/images/newmenubar.gif" USEMAP="#home">
The client-side USEMAP attribute specifies the location of the map information. In this case, the information is contained in the same document in a section called home This section is contained in a document structure tagged with the MAP tag.
