OGP Tag
{{ogp:title:Lorem Ipsum}}
Add OGP data to pages and blog posts with new tag
{{ogp:description:Lorem ipsum dolor sit amet, consectetur adipiscing elit}}
{{ogp:type:article}}
{{ogp:image:content/media/example.jpg}}
With a default image that can be set in the settings page.
Also, in the site template, use this and it will be replaced by the OGP information:
<!-- OGP PLACEHOLDER -->
It doesn't auto pick out any images. But this could be good for an update at some point.
