A few days ago, I saw a request for a way to share photos collaboratively and keep them private with the option of making them public later. My instant suggestions were Snapfish or Smugmug. While these are commercial companies that will allow you to print out your photos, it doesn't cost anything to post and store your images. The only cost is when you decide to have the pictures developed. You can invite someone to view an share your albums. It's all good.
And then along came Keepsy. This is
Keepsy for yearbook creation for your classroom? Parents could all chip in towards the payment of the order based on what they can afford and everyone gets a copy. This would also be a good way to gather your students artwork and create a hardbound keepsake. Of course, you don't have to publish it but simply Keepsy it as a digital album.
Oh, plus if that wasn't enough...they'll even gather your Instagram feed and turn that into a hard bound album.
