Michele,
You look to have another extension that's trying to do integration with Facebook. It's re-including the Facebook Javascript library (if you open the HTML and look for all.js, you'll see it) and also including the following line:
<meta property="og:image" content=""/>
That line is setting the image that Facebook should use as 'nothing', so Facebook is choosing it's own. Later on in the page, JFBConnect is trying to set the correct image, but the line above is overriding that.
Once you remove/disable the other extension, things should start working normally again.
Thanks,
Alex
Facebook isn't pulling the correct image for K2 articles.
