The question is more difficult than it seems. In general, my goal is to make some ecosystem in order to view images on PC from Android Phone or IPad/IPhone. Also view images on Android which stored on PC. Seems like it's a general synchronizing problem which can be solved by btsync. But I have some thoughts so may be there is another solution.
- As I know (I can be wrong) btsync works with files. So I should choose folder DCIM to sync photos. Btsync knows nothing about content, only folder synchronization. So how will synchronization be between Android and iOS devices? May be would be better to use some soft like Dropbox or Yandex.Disk which know about photo content and offer to include "Photos" for synchronization?
- When I imagine what I want I imagine NAS. It would be global storage where photos would be uploaded to and I could view images from devices via wifi/internet. (I also can be wrong here). What can you say about RaspberryPI+HDD as a NAS?
Sorry for uncertain question. May be you share your usecases. At the moment I inclined to think btsync is the best solution.
