{template_url} not getting parsed inside an included file

[www.girls-on-bikes.com]

Hello All,
I have a php include file that is used for adding my own links to the nav bar.
Say inside home.html, I have this:
<?php include("4gmenu.php"); ?>

4gmenu.php contains, among other things, some of the formatting from the original script, namely {template_url}
Now that is not getting "parsed" inside of 4gmenu.php

What would I need to do to get the {...} stuff to parse inside of a php include file?

Thanks

u cant, because 4images was designed to parse .html templates.
but u can try just use $varibales instead of {tags}
