Pinterest Image Fetch Broken

Anyone figure out a solution to the Pinterest issue? When someone tries to pin a post it shows a broken image in the pop up window. All my posts have an image in body and an assigned featured image. If I use the Pinterest Chrome extension it has no problem identifying the images on the page. Something about this plugin that needs to be tweaked.

If anyone has found a solution please let me know!
