I just tested this on my iPad 4th-gen, which is stuck at iOS 10.3 these days.

Safari cut-and-paste works for images.

Of course, as the iPad runs out of memory as I use multiple apps, stops Safari then reloads it when I come back. Which loses any edits to the content.

Expected. The unexpected is that this simple thing is as functional as it is...

Try using something like split screen to guarantee that the app will stay in memory.

(Good suggestion, but the iPad4 iOS 10.3 does not support split-screen apps.)
