I'm trying to have it so that when someone shares a Post from my website on Facebook, an thumbnail image shows on the Facebook post.  I have SEO by Yoast installed, but still cannot get it to work.  Common problem, I know.  Thanks.

Ok, not sure what happened, but it's working now.

Share on Facebook

Hi, I have a problem with the option to share on facebook in my portfolio. No image appears on the selected project. When I click on a project portfolio and give me a share in facebook logo gets anywhere. I've attached sample photos and the web link if you want to check.

Other social networks if they are working properly, Pinterest, Twitter, Google + ...

I hope your answer, thank you very much for your help
