Hi Alex,
Not currently possible, and may I know why do you need og:image
to a certain image in cornerstone? The opengraph data are usually placed within the <head>
tag. Not to the body nor to image itself, example,
<meta property="og:image" content="http://example.com/thumbnail.jpg">
And may I know which social media platform requires og:image
within the content and directly to the image? Perhaps I just missed something, but facebook doesn’t pull opengraph data from the content nor image elements, it pulls the data from open graph data placed in the head.
And if you’re trying to change SEO data, then I recommend using SEO plugin such as Yoast that you already mentioned, you can control how the data are displayed including images. But make sure to disable X/Pro > Theme Options > Social > Open Graph once you do that to prevent open graph conflicts.
Thanks!
