Custom logo as featured image (and used for links)

Hi

I use the “Mystique” theme and I have an .png set as custom logo, I found out that Featured images are used as “link images” when you post a link to the website at Facebook and other website. I would love if I could use the custom logo or another image I have uploaded as the “image link”.

I’ve made a post, saved it as a draft )not published) and included an Featured image in it and I’ll see if that has what it takes to be able to use that image when I link to my website.

Is there a plugin or some other solution for this ?
