Spun Theme Thumbnail Question

My question is for the author, Caroline Moore of the Spun Theme. I am using your theme for my final at school and I see that you have 15 thumbnails on the main page on your demo but only 10 will pop up for me. How do I get 15 like I see on your demo page? I haven’t tried yet but I will want the same spherical thumbnails on some of my posts as well…

Thank you much.
