After Yahoo sold Flickr, downloading my photos seemed near impossible. I had tried requesting zip files, which I did receive, but they wouldn't open. I managed to download many important photos one at a time on PC.
I was disappointed in the various Flickr apps on Android. None of them provided a way to download photos. A blogger gave me this clue: Go into your Flickr photostream and navigate to Camera Roll. From there, go to each date (I did it one at a time) and check "Select All." Request a zip file. When you receive the zip file, download it to your android phone.
To extract your photos, you will need WinZip or some other utility app. I downloaded WinZip from the Google Play Store. In WinZip, I selected "All Archived Files." It showed me the zip file I had just downloaded. I chose "Extract" and a location. It extracted my photos. I then went to internal storage and moved my photos to another folder (which I had already marked to back up and sync). After I had done all this, I went into my Downloads folder and deleted the original zip file.
I haven't yet experimented with choosing multiple dates in Flickr to zip and download at one time. It will probably work if I'm careful not to do too many and let the zip file get too big. Also, it's possible I could do it by album. I haven't tried that yet. I'm not surethecCamera Roll menu is accessible in Album view.
Anyway, I feel less panicked than before, but affordable, reliable cloud storage and efficient file organization are still issues for me to overcome.
