Genesis Simple Hooks Display Featured Image on Pages Only

I'm trying to get the featured image to show above the page content and below the navigation. I've gotten it to work but it is pulling the featured image from both pages and posts. I only want it to pull on pages (not posts).

Here is the code I'm using:

'format' => 'html',
'size' => 'full',
'num' => 0,
'attr' => array( 'class' => 'feature' )

I'm not sure how to make it work. I'm thinking maybe using the page ID #s but I don't know where I would put that. Changing the 'num' => 0 from 0 to page ID# breaks it.

I'm using the Dynamik Genesis child theme on a test URL I play around with. Here's an example of a page where it works.

Any ideas how to make it work on pages only...not posts? Thanks!
