Blog Images will not upload to social media platforms

I recently changed my WP Theme to Zee Corporation and it’s great, but I’m having one issue I can’t seem to resolve. After changing to the Theme I’m unable to get any Images to show up on my social media platforms I post in. These include Facebook, LinkedIn and Google+. The link and its written content uploads, but the image won’t. Additionally, it’s probably worth noting that not only will the image not appear these platforms they will show a shadow man and more often than not you can scroll over with arrows to choose a image. This is not happening at all. I researched and added a few plugins like WPSSO social share button thinking that would help and updated my PHP, but it didn’t do any good. My only option right now is to reactivate my old Theme to get images to upload on my social media platform and once done reactivate the Zee Corporation theme.

Can anyone recommend a solution to this issue? I’d like nothing more than to maintain this a my new theme, but without being able to upload images the theme for all its great look simply will not work for me.
