php code in templates

[webgod]

I'm a programmer by profession, but I am still trying to get the hang of Vbulletin.

here is what I am trying to do:

I'd like to place a snippet of code in the footer template that creates an array which israndom sorted then spits it out the resultants...

basically I'm randomize the display order of ~ 50 images.


The code works perfectly in a standalone php page...
however when I insert it into the footer template, it obviously does not.


so my question is, what is the easiest way of achieving my result?


here's a snippet of the php code structure:

PHP Code:

$randimgs = array (
"<img src='1.jpg'>",
"<img src='2.jpg'>",
"<img src='3.jpg'>",
"<img src='4.jpg'>");

srand((float)microtime() * 1000000);
shuffle($randimgs);
foreach ($randimgs as $randimg) {
    echo "$randimg";
}
