Facebook shows only link to post

Hello,
On this site, https://getlucid.net/blog/ when a link to a post is pasted into Facebook, sometimes only the link shows. Some posts were not showing images, but in at least one instance, the image was too small (less than 200×200). We are using NGFB Open Graph+ to generate the OpenGraph Meta tags.

It seems very inconsistent, some work, meaning they show the thumbnail, a text excerpt and the link to the post, and some only show a link. Naturally we assumed that there was some difference in the posts, but nothing really stands out. In searching this forum I have found some similar problems but no solutions that are applicable yet. If someone has had this problem I’d love to hear the solution. We are using WordPress 3.8.1 and all plugins are updated. I have posted some results from Facebook debugger below for a post that showed the text excerpt but no image. The image size is 205×205. Thanks for looking.
