I am having the same problem: when using the Jetpack share button for Facebook, Facebook pulls the wrong image. My posts each have their own featured image. Each image is greater than 200x200px.
I am using Yoast WordPress SEO and have “add open graph meta data” in the Social section checked.
The Sharing and Related Posts features of Jetpack are the main reason I use Jetpack.
An example post that pulls wrong image is https://blueoakschurch.org/athome/hope-difficult-abusive-marriage/
Putting this in FB Debugger shows that properties are being inferred and need to be defined. I thought WP SEO would do this. I’d prefer not to have to paste in the same image 2x in each and every post (once as featured image and once in the SEO social settings).
I found this article that recommends adding code to my functions.php but I am reluctant to try it.
Any help?
