featured image showing up in search

Hi, great theme! I am running a recipe blog and when you go on the blog and use the search function, the recipes come up with space for the featured image, but no image. http://www.gardenfreshfoodie.com/?s=stir&submit=Search Here is a link to what I am talking about. There are 5 recipes that match the search, but none of the featured images show up. Any clue why or how to fix? Thanks
