This is the text I integrated in that page:
{SCOpenGraph image=http://integralzen.de/images/doshinjunpo.jpg}
{SCOpenGraph title="Junpo Roshi und Doshin Roshi zu Mondo Zen"}
{SCOpenGraph description=Junpo Roshi und Doshin Roshi erklären jeweils aus ihrer Sicht, was Mondo Zen ist.}
{JFBCLike}
So I see all three og:image tags on the page from the JFBConnect block of tags. Multiple images are allowed on the page. How are you adding the other two images using JFBConnect, if not from easy-tags?
