You’ll probably need to float or position it to the right with CSS when it’s showing up.

Code is:

It should look like this header http://accessc21ri.com/

function custom_header() {
?>
<a href="EXTERNAL LINK HERE"><img src="<?php echo THESIS_CUSTOM_FOLDER; ?>/images/header.jpg" alt="TEXT INCASE IMAGE DOESN'T SHOW" /></a>
<?php
}
remove_action('thesis_hook_header','thesis_default_header');
add_action('thesis_hook_header','custom_header');

You would need to be pretty clear as to where it was linking as I think most people expect the header to link to the home page of the current site.

Odd question–is there a way to use the clickable header to link somewhere besides “home”? Is it possible to link outside of yr site?
thanks
