remove button link at the bottom of checkout_success page

I have just installed MS2-MAX V1.70! Everything is working fine except for the continue button link at the bottom of checkout_success.php page. It’s looking for my secure page and not switching back to regular URL. But everything else works just fine so I would rather just modify or remove it completely. Anyone have an idea about how?
In my catalog configure.php there is nothing that defines ‘DIR_WS_TEMPLATES’
But in the catalog configure_bts.php there is this:
// BTS defines added 2003/12/23
define('DIR_WS_TEMPLATES', $tplDir . '/' ); I have this defined in my admin.
require(DIR_WS_TEMPLATES . TEMPLATENAME_MAIN_PAGE);
In my admin configuration I have the following.
Allow template switching set to false.
Subdirectory (in templates/) set to osC.

Instead of changing anything How can I safely remove this continue button link from the bottom of checkout_success.php page and which page or pages would I change? Or How could I html code it with <a href="http://return to cart index page"><img src="/images/continue_button.gif" ALT="Return to Index Page"></a> link?
Thanks,
Jacob
Also is there any overview or documentation that explains how the templates interface with the rest of the cart pages?

I think you can do that in checkout_success.tpl.php
