Unable to get this Plugin to function at all

Hello. I am loving the concept of this plugin. However, I am hoping to use it to create a lovely layout on my home page for the salon I am employed with.

The Goal would be to have the featured images for each page displayed in the layout as a clickable button to navigate to that page with.

I do not want to display posts.

I tried the [autonav display="image"] with no luck.
