bbpress post image for facebook

Hi

I am using bbpress that comes with a feed feature where a user can post something like facebook.

After a user posts on the feed with an image, I tried to share the post link to facebook. but facebook doesnt take the image from the post but the featured image of the ‘feed’ page.

Is there a way to assign an img metadata to each post whenever a post is made with an image in order for facebook to crawl the image when sharing the post link on the fb?

Please advise.

Thank you
