How to change website display photo?

Hello,

I am just wondering how I can change the photo that displays when I share my website URL. For example, this is the photo that displays along with my website when I am sending someone a link to view my site:

http://icreativedesign.net/wp-content/uploads/2013/04/Screen-Shot-2013-04-01-at-7.50.03-PM.png

I do not want this photo to display with my site. I would love to see my site logo or another image display in space of what is currently there.

Any suggestions?
