I have been having this problem with Facebook not displaying my photos or videos like this. I did a lot of searching for a solution. Facebook is no help because they are to busy to respond to any queries. I went to their community forum, the help forum, and finally WordPress who suggested I check with the author of the Jetpack plug in. I got an answer that the problem be with a conflict with Jetpack and the All in One SEO plugin and that I should check my setting in that. So I went into that set up made some tweaks and I thing may have solved the problem. I am going to post this entry and see if the picture in the upper left shows up in Facebook than I will be good to go.
