I have an old iPhone 4 that I'm about to ditch. It has a couple of hundred photos on it, and I briefly looked into a way to access them directly from my Xubuntu laptop. (I no longer have Windows or Mac machines.) However, I decided against that route and decided to open an iCloud account, back-up the photos, and download them from iCloud through my browser. No problem, right?
Except that there does seem to be a problem. In iCloud.com it states that my iDevice need to be running iOS 8.x (don't remember the exact sub-version), and my phone is running 7.x, so I guess that's why the photos don't show. So I thought I could get them from the iCloud Drive and download them en masse without the benefits of pretty thumbnails, but there's nothing there either, despite the fact that apparently about 800 MB was uploaded from my phone.
I'm looking for suggestions on how I can get these photos off this ancient iPhone, or out of iCloud if they're in there somewhere. Thanks.
