I really don’t understand exactly what you are asking. I think OG codes have something to to with google or facebook? I don’t know much about them.
But, if you try to look at the link https://polywogg.ca/wp-content/uploads/2020/12/header-7-family-gallery-1024×213.png, you get a 404 WP page. That generally means that the image does not exist in your media library. If that image existed, then it would display by itself in the browser.
At this point, all your issues could be the fact the image simply does not exist at that URL.
