|you are doing.                                             |
|                                                           |
|To display the random image on your web page, you can      |
|either copy and paste all of this code into the page where |
|you want it or you can include it by putting in the        |
|following code into the page where you want the image:     |
|<?php include "image.php"; ?>                              |
