Dynamic Avatar

Or in other words, a random image.

Quickest way probably to do this is to create a directory and place a series of images in it, naming them with sequential numbers, eg: "1.jpg", "2.jpg", "3.jpg", etc...

Next create a blank PHP file (in the same directory), call it something like "image.php" and put this in it:

<?php
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");   
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");   
header("Cache-Control: no-store, no-cache, must-revalidate");   
header("Cache-Control: post-check=0, pre-check=0", false);  
header("Pragma: no-cache");  
header('Content-type: image/jpeg'); 

$rand = rand(1,24); // Where the rand is between 1 and however images you have in the directory

$im = imagecreatefromjpeg($rand.'.jpg'); 

imagejpeg($im); 

imagedestroy($im); 

?>

Then you can use it as a normal image, e.g.

<img src="image.php" alt="Image" />

You could also use it on forums and other websites as an avatar, however it is unlikely that they will let you link to a PHP file (unless their security is poor), so to get around that we need to go into the .htaccess file (which should be in your public directory) and add this in:

RewriteEngine On
RewriteBase /

RewriteRule image.jpg image.php

Now if you goto "image.jpg" in the web browser, it will load up the image from "image.php".

See below for example ("avatar.jpg") (Click to refresh)
