I use Google Photos for all photos I take. When we have an event, friends and I tend to share photos to each other, using Google+. I can see the photos fine - but I really want a way of making them part of my own photos library.
Ideally, I'd like to just say "automatically absorb any photos or albums shared to me" - but failing that, I can't even find a manual way, besides what I'm doing at the moment, which is individually downloading every single photo and then re-uploading it into Google Photos.
Is there a way I can automate this?
