Image Map
There are in fact two major types of Image Maps: Server Side: This is the older method of doing image maps. The reason for finding out what type of server you are on is so you know what format to make your map files in. Client Side: These maps are implemented by placing the map coordinates in your document's HTML code. This method is supported by most modern browsers. It is much more efficient than the Server Side map in that you do not transmit mouse coordinates back to the server. Most of this page will be dealing with this type of mapping.
