Timthump.php Grabbing Images on Homepage, not Post Pages

Hello,

I’m having some trouble with using timthumps.php in my WordPress Network site. You can see on this page on the right sidebar below the Facebook like box the images are working:

http://nfl.rantsports.com/

But on a post page, the images are not. And I’m using the same code for both:

Thanks,
Grant
