front page blogs picture and text not visible, only subject is visible

Hi,

Just started with theme Network, there is a nice guide in it to get started, but… only in pages I can cloice/ set -new blog- When I create a new post with featerd photo only the subject appears. Question,1- frontpage blogs is a post or page, 2- Why is the picture and text not visible?
