Facebook og:image

I’m running the Facebook plugin v1.5.3. Its generating 2 og:image metas which is screwing with my posting to facebook. Is there any way to force this to only use the first image?

As an example, I run an automotive blog, today I posted about a person and then the second image in the post was a different person. Since the blog post was about the first person, seeing the post come up on facebook with the second person on it doesn’t make a whole lot of sense. When posting it as a new post I can select the image I want which is all well and good however if I reply to someone my post it shows the second image.
