How do I put featured image thumbnail from a page on the main index in wordpress
===

I am trying to put the featured image from a page on the main index page of blog along with the with featured images from posts (post featured images are already there). For longer posts I want to be able split them up into multiple post, put them under one category, put that category page on the main index and then have each of those on that category page. 

Here is the site:
