images photography flickr private

Hi there,

I have a specific use case scenario that I am trying to solve the smartest way possible. We have a preschool where we'd like our teachers to take photos on a smartphone and upload them to our Drupal website rather than messing around with a bunch of SD cards! The catch here is that the images need to be completely private as it's a preschool. Ideally, parents would log into the website and see their kid in a gallery having a great time. I understand this is possible in Flickr but parents would still need to join Flickr and login twice. (?)
