Single image Facebook sharing - HELP

Hallo Community,

After the publication of my last website made with Webflow the Client asked a extra function.
They want a Facebook share button for a single image of gallery.
Here the gallery page Jabba / SSD tattoo artist portfolio

I did a deep research but without results :confused:
Someone knows how it works?

Here the read-only link to my project.
