Weird Categories code?

Hello,
One of my Categories contains just posts with pictures. They show up correctly on the main blog page, BUT not under Categories that they are in. Under the Category you see no graphic, but this code:

addthis_url = \’http%3A%2F%2Fsunruby.com%2Fportuguese%2Fsan-jose-portuguese-day-june-14-2008-4\’;
addthis_title = \’San+Jose%2C+CA+-+Portuguese+Day+-+June+14%2C+2008\’;
addthis_pub = \’\’;

Main page view:
http://sunruby.com/

“Portuguese” Category view:
http://sunruby.com/category/portuguese

Thank you for any help!
