Random Header

[Mile-O-Phile]

I have created a template with the following code:
<?php include('random.php'); ?>
The idea is that I want to replace the static graphic atop my forum with this .php page that will return a random image. How do I go about editing templates, replacement variables (?) and the like so that it happens?

You can not use PHP in templates.
