Are you referring to sharing a post on Facebook by hand, or are you talking about choosing an image for Publicized posts?
When I share a post by hand I can choose an image:

… but when I Publicize that post, an image is chosen for you since it has to be done automatically.
Let me know, thanks! 🙂
I am reffering to Jetpack sharing module.
“Share your posts with Twitter, Facebook, and a host of other services.”
And I use Facebook button from this module.
First i thought Yoast SEO is making this. Had disabled Jetpack Open Graph with one line in functions.php.
– Delete line
– Disabled Yoast OG-
– Deleted web cache, browser cache.
– I see in source Jetpack generates its OG.
It is the same as OG from Yoast. And still only featured image to share on Facebook.
Maybe worth repeating again, they are images from WordPress gallery shortcode.
With featured images, only featured are picked for FB.
Could you post your site URL here, so I can have a look?
If you want it to remain private, you can also contact us via this contact form:

I just sent you a URL there. Yoast SEO OG is activated again.
