Clearing text float around images

Hi,

I've searched around for a bit and I can't find a reliable way to do this. How do you make headers not float around images the way they are doing on, for example, the Transistor character page (under "Other Characters")?

The way to fix the problem on that page is for the character entries to actually have more than 1 or 2 lines of content. Then there might be enough text for the images to actually fit in the headers.
