Smaller images collected break the featured section on main page

Hi,

First, thank you for the great support! I have been using the Autoblog plugin, and had great success with it. A small problem I have is, since it imports from feeds, if the image imported is small, it breaks the featured news section on the front page. Please see below for an example;

Now I know that this is mainly related to the theme but it would be very nice if we could adjust the image sizes (we can sacrifice quality, as long as it displays correctly) properly for this theme. Thanks a lot for your support!
