Since I keep in contact with most of my family via facebook, have you thought about making this work as an app? I know facebook has photo sharing already, but it is pretty unorganized and you can't have shared albums without creating a group (let's face it, most families aren't going to do that). Also I think having the functionality to embed the slideshow in a facebook post would be nice as well.
My thoughts.
