image: not being read when posted in social networks

[Delvis]

In themes I've used before, when you post a blog or other page section in a social media like facebook, twitter, and so on, it automatically shares with the associated image defined in "image: /image/example.jpg" in the head of the .md file.

Does not seem to be working with hugo-profile (I tested in several social networks)

It also fails to provide a general image for the entire website as an alternative, this could possibly be the image defined in config.yaml
Hero:
image:

Or a new parameter could be created for this.
