The short answer is probably .
This will depend on the theme and/or SEO plugin.
If there is a place where the featured image would be used. DFI will fill it in if missing.
So google/social share will look for both regular images and
<meta property="og:image" tags in your HTML.
So if your theme/SEO plugin adds that, DFI will automatically do it’s job.
Hope this helps you.
Let me know if I can do anything else.
