IF statement in ad_navbar_below ad location template

[AshMagic]

Hello,

I was wondering if it was possible to add an IF statement into the ad_navbar_below ad location template so that it shows different ads on different pages.

For example, I want my Google adsense text ad code on all pages except the arcade.php page. On this page I wish to display a different ad type. So could there be an IF statement in the template saying:

IF page = arcade.php
//image ad code here
Else
//text ad code here

I hope you understand what I mean. Any help would be great! Thank you.
