Image Maps Client-Side vs. Server-Side

Image maps can be of two types: server-side image maps and client-side image maps.   Each has advantages and disadvantages.

• In a Server-Side Image map, the server, controls the image map.  They are supported by all browsers but they tend to be slower to operate, increase traffic load on the server.   Some Internet Service Providers do not allow server-side image maps.  The Packard server does not allow you to use Server-side image maps..     
   
• In a client-side Image map, you insert the image map into the HTML file, and the image map is processed locally by the Web browser.  They tend to be more responsive than server-side maps, because the information does not have to be sent over the network.    Some older browsers do not support client-side image maps.    Directions and assignments in this unit refer to Client-side image maps exclusively.
