I updated the LinkedIn with the code you provided that other individual which fixed that issue.
The issues that still remain:
Google+ and Facebook both pull the Related Article image instead of the Featured Image
Email does not include a link to the article
Hi,
I am not getting your issue exactly. Please explain with marked screenshot image. I debugged and found with facebook debug toll and not found any issue like this.
I think the issue with the email not including the link is the length of the excerpt text. I’ve limited this for the next update. Send me an email via: http://themeforest.net/user/swiftideas if you need this sooner.
As for the image, you’ll want to install the WordPress SEO plugin, as this will add the social meta tags to the header to use the correct image.
