How to Show Site Wide Post Picture in the Front Page


I use corporate theme. On the center of my homepage, I use center widget with Site Wide Post widget. I noticed that if a picture is presented before a text in a post, it appears in front page but if the article is written first before a picture is posted, it doesn't show in the front page (check attachment for better description).

How can I show picture (like attachment) without picture first on a post?
