David,
On that page, I'm not seeing the og:image tag that JFBConnect should be inserting. That makes me think the Open Graph jReviews plugin isn't doing it's job on that page. Can you check and make sure the category or directory is set correctly to one that contains that listing? If so, then also check to make sure there are no Open Graph - Content objects defined for the same category/article. If so, that object may be 'winning'. I'd just unpublish any other objects you have configured, for now, to test with.
If unsure, try changing the 'type' of the object to something like 'lkjlkjlkj' and see if the debugger gets that. If not, then the object isn't applying and you'll need to figure out why.. or private message us admin credentials to your site and we can look at your settings to see what's going on.
Thanks,
Alex
