Cant post urls so the src is different than in the rendered html but:
<img border="0" alt="Dana Lightspeed - maybe the kewlest girl on the net!" src="/wp-content/uploads/2006/04/dana-150x150-2.jpg">
Image broken, FF wraps the alt text but IE and Chrome dont which makes the left column a lot wider than it should be thus messing up your layout. Right column has same problem with broken images and long alt texts.
