No, it's not currently possible to push photos to Facebook. If you have a developer, we do implement the Facebook API, which means they could manage to implement such functionality, but it's not a built-in part of JFBConnect right now.
We're looking into the features for 4.1 and 4.2 right now. We're hoping that a more automated push of content back to Facebook will be in the 4.2 release, which is still a few months out, but even then, the roadmap isn't locked down.
Good luck,
Alex
