Requirements:
XenForo 2.2.15+
Description:
Brings back the old behavior of displaying an image in linked data for search engines
The latest version XF displays the first post attachment thumbnail in threads as a preview image for data rich display in search engine results.
This add-on allows you to make this optional by enabling it only on your preferred forums. By default, the author's avatar will be displayed if available (as it was before version 2.2.14)
