This extension provides fields in both the SiteConfig and on Page. The SiteConfig image is the default fallback for all pages but one can customise which image appears on each individual page by using that page's facebook image field.
$ composer require heyday/silverstripe-facebookimage
<html>
<head>
$FacebookMetaTags
</head>
<body>
<p>Hello, world!</p>
<body>
</html>Use the $FacebookMetaTags variable in your silverstripe template in the section.
