am I wrong or does this plugin add the first image it finds as the og:image? Could it be modified to check if a post has a featured image and take that if it exists, falling back onto the first image of a post if there is no featured image?
Also it seems this plugin defines the full-size image as og:image, shouldn't it rather take the thumbnail version?
talking about og:description - can this be changed to use the meta description that some SEO plugins create? i.e. AIO SEO pack or others?
and btw. does Gogle+ also use the same opengraph data?
