WordPress Posts aren't adjusting to images?

I’m helping a friend with a blog he is starting and for some reason I can’t get the posts on the main page to adjust to the images. The blog is http://www.swagspot.com/.

I’ve been looking at it for an hour, but need to get back to work and was hoping some Fluther-ites with CSS Jedi skills could lay fresh eyes on it.

Any help is appreciated & thanks in advance!
