CMS Image shown in editor, but not on live site

I am using the Nero template and it has worked up until this point. Now, whenever I look at the live site, the images shown in the top right for my CMS driven portfolio disappear. They are shown on the editor, and it is whatever two happen to populate those two top right boxes, so it is not unique to those two image listings. In addition to this, the images are loaded on the live site (I can right click them and view the image in another tab, but they are not being displayed on the live site iteself).
