I'm having some trouble updating my preview image for my blog. If I post a link to facebook it's showing an image that I no longer wish to use. I have already changed my gravatar, avatar, blavatar, hover image, blog image, profile image, and I have deleted cookies, cleared cache, and removed the old image from my account. I am out of ideas.
The blog I need help with is frompennieswithlove.wordpress.com.
