If images are float left on a listing/blog page and the next item doesn’t break below the image but continues to wrap around it, you need to add a float:left and clear: both to a class in the style.css.
See below
#featured-bottom .featuredpost .post, #featured-bottom .featuredpage .page {
margin: 0 0 10px 0;
padding: 10px 0 15px 0;
border-bottom: 1px solid #333333;
   float: left;
   clear: both;
}
