The only option that I know of is Dropbox. they're a classic player in this space with an acceptable track record (afaict). They have a nice app with auto-uploading of pictures, they dump them into a single folder with zero modification, preserving all metadata. Creating a photo album to share is as simple as putting all the jpegs into a folder and choosing "share" in their UI. You can create share links with the usual expected gradients of public accessibility, or you can share them with only specific authorized Dropbox users.

Minor nitpick: Dropbox doesn’t preserve the original filename (e.g. IMG_1234.JPG), instead changing it to a timestamp-based filename. It also doesn’t preserve Live Photos on iOS.

You're correct, turns out Dropbox does rename the files and I'd forgotten.

It seems you're right about some quirks in their automatic photo saving system on iOS. Ive been using them with Android exclusively and had good support for auto saving pictures of all kinds.

OP, if you're on iOS Dropbox may not be for you.

I do use paid Dropbox on iOS and aside from the two defects I mentioned, it’s very reliable. Actually there’s a third: the Dropbox iOS app cannot reliably run in the background, so mass uploading is only possible when the phone is plugged in and the screen switched on with the app in the foreground (e.g. overnight) - but this is the fault of iOS.

Is there an alternative you’d recommend? I also use Dropbox for its cost-per-TB and Linux client.
