I think it would be a nice feature if we could post some images uploaded here to a Facebook account. Aminus3 gets exposure to new people, Facebook book gets quality content and the customer gets a easy interface. Just a thought, seems like a lot of photo sites are expanding in this direction.
You can currently integrate Aminus3 and Facebook using your RSS feed. All Aminus3 blogs have an RSS feed located at feed://<YOURDOMAIN>.aminus3.com/feed/images/
As for a tighter integration, we don't have anything in the works at this time but welcome any ideas.
I use an app on facebook called RSS Graffiti for this purpose. It is a pity that you can't choose the time that your photos appear, but other than that it is quite functional.
Not sure if I'm missing something here, but the Networkedblogs application on Facebook seems to me will do the trick. A little bit of work to get accepted, but after that all images posted on Am3 get uploaded automatically.
