There's an Instagram integration feature available now. If I understand it right, that would at least alert your group when something new was posted to the Instagram account, I think? I haven't tried it so I don't know for sure. A little round-about maybe, but if you try it, let us know how it goes.

I wondered whether integration would offer us some of the features we wanted - e.g. photos.
