Help with buttons in the header

[Guest]

I'd like to remove the shopping cart, account, and checkout buttons in the header so that my image spans the entire length of the header.

 

http://www.autooutfittersonline.com/osCommerce, i'd like the logo image to span the entire length of the top, and not stop when it reaches the buttons, if someone could instruct me on how i could go about getting rid of the buttons i would really appreciate it. thank you for your time

Look in /catalog/includes/header.php

I tried deleting the parts of the header.php file but it just ended up getting all screwed up, if you could be a little more specific on what to edit in the header file it would be most appreciated, thank you for your time
