I would like to know, how to change (where to change) in UNA platform what is used as share image when someone share content from UNA site to Facebook.
For example, if a content from your UNA site is shared to FB it looks like this:
but if I do a sharing to FB from our UNA based site it looks like this:
So, where, and how to change this picture used for FB sharing?
It uses your site logo by default. But this will be used on all sharing not just facebook.
Depends on content item actually. We can “suggest” media to use for FB, like, say, cover image in a post, or a profile pic in profile. In this example discussion doesn’t have an image of any kind so FB is pulling the site icon
