Ask HN: is there an alternative for instagram?

something like ownCloud hosted on my own server, but not just a gallery-skript, but connected with an app to share photos easy from my phone? What features should such a solution need?

As I understand openphoto you still have to store your private photos on public cloud-services? But if I have my own server I like to store them there. I feel better if I control who can access my photos.
