Images not showing when share to facebook, Twitter, Google Plus, et al..

Hi! And happy belated birthday, Mark! I am having an issue where the blog image doesn't show when I share on social. I saw the others on the forums have this issue, and I followed all the advise that I found, but still no image showing when share. Ideas? If I don't get this article out today, it gets trashed. And I can't get it out without an image. Anyway, I know it's your weekend, so no worries if you can't get to it.

Cheers!
