extra og:image tag

I was told by Shareaholic that this is an issue, but I don’t now how to resolve it –

You do have Open Graph Tags set on your blog. The conflict is that WordPress Facebook Open Graph protocol plugin (WPFBOGP v2.0.7) is setting two og:image tags, and the second one is being used, which points to http://www.pghlesbian.com/wp-content/uploads/2012/10/MyBLOGLOGO2.jpg . Take a look at the settings for this plugin to see if you can locate a way to remove the extra og:image tag.
