The FANTASTIC McFantPants created a sidebar badge for all participants. You can see it in my sidebar (top right!) and here's the code:
<a href="http://www.shelikespurple.com/shelikespurple/2011/01/biggest-blogging-loser-roster.html"><img src="http://www.shelikespurple.com/biggest-blogging-loser-150x150.png"></a>
The image will link back to the roster page, so everyone can see who's kicking (and losing) so much ass.
