Image Map Mechanisms
- Server-side image maps
- Older technology
- The browser sends the pixel coordinates
of the mouse click within the image back
to the server; the server then redirects
the browser to the corresponding new web
page
- No longer commonly used
- Client-side image maps
- Simpler -- the pixel coordinates reside in the web page itself
rather than in a distinct file
- Less work for the server -- the browser does it
- Hovering the mouse, the user can see the URL
associated with each area
