How do you publish a picture to an event with facebook opengraph?

I am able to successfully publish an event to facebook but am unable to include a picture. It looks like this needs to be done via a "connection" i开发者_如何学运维n open graph but I can't seem to find a clear example on how to do this.

Yeah, the picture connection appears to be read-only. However it wouldn't hurt to try sending an HTTP Post to /{event id}/picture and seeing if it's just an omission in their API documentation. My guess is that it is not available.
