I'm looking for something I can set up where myself and one or more other people can select photos on our devices and share them with the others, with all the devices (Windows & Android) having the same automatically-synced set of photos without any intervention.
Let's say I take a photo and select to share it, it then automatically (perhaps with a notification) appears in an album on the other person's device without them having to visit a website, and they can do the same for me. Maybe having the full-size pics stored online would be better and just a thumb gallery held on the devices, so each device wouldn't get full up, I could just download the images I want to keep, for example.
I have a domain with "unlimited" webspace and script capabilities, but I don't mind paying for a "cloud" service & apps for the devices if there is a suitable service out there. Google+ photos? Dropbox? Can you sync 2 or more people's photos this way? Anyone else done anything similar?
