Cyndi and I use flickr to host our pictures. I think it is a great deal: $25 for a whole year and unlimited pictures. But there is no automatic way to get pictures from our Android phones onto flickr. Google has built this functionality into their google + app. Western Digital has an app that will upload pictures to certain types of their hard drives. The flickr app doesn’t support it. Google used to provide unlimited space for full size pictures if you had a plus account; however, they changed that and now only provide 5GB space free for full-size images (unlimited for 2048×2048 size images).
Yesterday, Amazon sent an email about their new Cloud Photos app. They’ll give you 5GB free; however, it links in with their Amazon Cloud Storage. About a year ago, we started paying Amazon $20/year to let us upload our MP3 collection to their Cloud Music Player app. Think flickr but for music. And, along with that, we also get 20GB cloud storage. They’ve changed the program slightly since then…Current prices should be here. We weren’t using but 10MB of the space for a small truecrypt volume holding our passwords and had loads of space.
So, from using it for 12 hours, the app will auto upload pictures to your Amazon Cloud Drive (both on and off wifi). You can also choose pictures to upload. When you look at your cloud drive, you get some organization; however, I’ve yet to try it with multiple devices.
At this point in time, I would certainly recommend the Cloud Music service. If you have a subscription to that service that includes space you aren’t using, why not?
