attached image

First Off I want to say this is an amazing theme, thank you!

Im having a little issue with it grabbing and attached image and setting it as the thumbnail.

I’m running an ifttt script to share post across various social medias, all others run without issues, When a post is shared from any media (tumblr,twitter,facebook) to my wordpress it doesnt display the attached imageas the thumbnail. I run the same script on various sites with different themes and dont seem to have this issue and REALLY dont want to change the theme.

Thank you in Advance
