I was looking for something like this - does this process remove the photos from the phone (freeing up space) but keeps them visible in the integrated gallery app as described? or like dropbox, is there a copy in each location?

I hate Google+ and don't want anything to do with it, but at the same time, I can't find an app to integrate my photos that I moved to the Amazon S3 cloud with my phone, even as a third party gallery app.

If this option really works, it would be worth considering as I can still archive my photos to S3 for pennies a month so it doesn't matter if I delete photos from Google.
