Update: Facebook is showing the wrong image?
Facebook has an option “Let Facebook fill the link infoâ€. If this option is selected, Facebook will decide what image to take by itself and ignore all plugin settings. Facebook takes it’s info from og: metatags, so make sure that those metatags are configured on your site. Please see Facebook FAQ #4.19 here for more info
