Image trouble

Recently my blog posts have begun to show up in FB posts and Outbrain images with the same image for every post, possibly drawing from the author image rather than the images within the post. I have been looking through my plugins and my settings trying to determine where something changed or needs to change and cannot find anything.

I am unsure if this began at the same time that I updated to 3.3.2 or if it coincided with another change (such as a plugin). I deactivated a plugin that would show the author gravitar with each post but the problem continues.

Any ideas? Thanks!
