Dynamic Headers plugin setup

Hello,

I installed the Plugin “Dynamic Headers” because I want to have different headers images on different pages of my WEBsite. I am using the Twentyten theme.

The instructions call for me, as a last step in the setup, to drop some HTML code into the header.php. They say that the location of where this code should go depends on the Theme. I have NO idea where to put this code! THe code is supposed to add a template tag to the theme file where I want my dynamic header to appear. The HTML code is: <?php if (function_exists(‘show_media_header’)){ show_media_header(); } ?>

Any idea where I should put this?

THanks.
