Thanks for the replies.
The version is 13.2.3 on iPhone Xs and my iPad Pro.
I am trying to save free domain images, such as from Wikimedia Commons. (Btw, screenshots and such are not what I need, but the ability to save a high rez image directly to photos).
In previous versions it was a simple press and save to images. I have friends that can save the exact same images (using the same iOS version) with no problem, and they cannot understand it either. No such option appears on any of my devices. (As I said, all that appears is 'Share' and 'Copy', and Share only allows to text, email, add to reading list, etc.).
It is very frustrating that no one else seems to have the same issue or a fix for it.
