I am trying to install a "digg this" button in a sidebox so customers can post pages to digg regardless of what page is loaded at the time. Sorting out the operation of Kuroi's blank sidebox mod is pretty straight forward so far as the button is concerned, but digg provides a small script that does not work in a sidebox, and, according to them, should be installed in the header so it loads first and references the button faster when the button(in the sidebox) is loaded. My initial thought is to put this script in the "header.php" file(name association, header) and am wondering if this would be considered acceptable, and if so, where in the header.php it would be best inserted. Here is the short script they provide:

<script type="text/javascript">
(function() {
var s = document.createElement('SCRIPT'), s1 = document.getElementsByTagName('SCRIPT')[0];
s.type = 'text/javascript';
s.async = true;
s.src = 'http://widgets.digg.com/buttons.js';
s1.parentNode.insertBefore(s, s1);
})();
</script>

Any advice or input would be appreciated.

P.S. I've tried running the script from the sidebox and it locks the site up.
