Mempership Wordpess Plugin images not showing for guests

I have Membership plugin installed on my site and I have a guest level access with negative and only one menu item on the negative permission list so they can see everything else. When I go to some of my pages for example http://www.clarkwholesale.net/about-us/ as a guest, I can't see the image in the content section. I tried deleting the image and re-uploading it as well as saving the editor in html mode.
