Start page, no thumbnails

I've looked through the other questions regarding this issue in the forum, but can't seem to solve the problem.

I'm using Biblio, and for some reason no thumbnails are showing up on my start page. I've tried re setting my start page to "none" so it will default back, but for some reason that is not working. The only thing showing up is my header image.

Thanks so much
