ad code

[Bigguy]

I would like to know if someone can tell me were to put this piece of code in smf 1.0.5 so that it shows on all pages of the forum at the top of the page.

<?php include("http://www.x10hosting.com/advert/quick_get.php?id=corporate") ?>

I would imagine it goes in the index.template.php file somewhere, just not sure were.
