I set the featured image 300x300 and then insert a thumbnail 150x150 of the same into the post.
With Wordpress Seo Social turned on I then get 2 meta property='og:image' entries. First the featured image and then the thumbnail 150x150.
Including the function // Tell WP SEO to use a larger thumbnail there are still 2 og:image entries. Only difference is the file name has the 300x300 included in the filename without the function file fix.
So is this how it is supposed to work?
