This documentation is not using the current rendering mechanism and will be deleted by December 31st, 2020. The extension maintainer should switch to the new system. Details on how to use the rendering mechanism can be found here.

User Manual

Operating Instructions

The content of each Open Graph property is taken by this priority:

Property first second third
title local page-title
image local page-media global
site_name global template-sitetitle
description local page-properties global
url generated
locale generated from config.locale_all if available

For example the extension tries to render the image-property:If there is no image defined local within the page-properties, if tries to fetch a image from the global TypoScript Settings. If there is no image, too, no image property will be rendered.
