We're beta testing our upload API for MyShoebox and would love a few devs to check it out (shoeboxapp.com). We offer unlimited free cloud photo backup (of course there is a paid plan as well). Part of our mission is to unify your photo collection across all your devices. We have apps for OS X, Windows, iOS and Android but there are dozens of other platforms we'd love to be on. If you're interested in writing an uploader/app for Linux, WinPhone, Blackberry or anything else email me a brief description of what you'd like to build and we may give you early access to our API. Priority will be given to open source projects and automatic uploaders.Email: scosman [at] shoeboxapp [dot] com
