- The browser sends a HTTP request to the server.
- The server returns a HTML web page that contains an <IMG> tag for the image,
and the <MAP> and <AREA> tags for the image map.
- The browser receives the HTML web page. It then sends another HTTP request
to the server using the URL in the <IMG> tag for the actual image.
- The server returns the actual image to the browser.
The "some place" can be a "temporary file" or a "session variable". The clickable examples in this documentation will be based on the "session variable" approach.
