Hi @BET_ventures, my guess is that there is some server caching going on somewhere, that when Facebook is retrieving the URL, it is getting old info perhaps from a previous crawl of your site. The issue might solve it self in time. The code with the FB share button is good, I don’t think there is any problem there.
Here is what I see on the site that was missing the image:
One thing though on the site where the image is not showing, I only see one image on the page, the logo. There is a background image, but FB only work with image widgets, it will not read the background image.
I hope this helps. If not, please let me know – I’m happy to assist further! 
Cheers,
Dave
