header.php question

I need to add this piece of code for an affiliate banner and link:

<img border=”0″ src=”https://banners.bookmaker.com/images/book_football_468_60_0.gif?cmpid=7165_426″&gt;

into this section of header.php:

<img src=”<?php bloginfo(‘template_url’); ?>/images/468×60.gif” alt=”Featured Ad” />

at this site:
https://www.atsbookstore.com

I’m not exactly sure where the affiliate info is supposed to go.

thanks for anyone’s help.
