There's no official minimum but I'd say that to be useful they should be no less
than 2000x1000 pixels. They should be highest quality jpg (i.e. not degraded quality, as
that introduces artefacts).

Hello!
I am in touch with a museum that is thinking of uploading images to Commons. They are a
bit uncertain about uploading high resolution, but I told them the resolution they need to
upload just needs to be good enough for illustrating articles without being pixellated.
The thing is, I am unsure about the minimum size of such an image. I tried poking around
the instructions but didn't find a direct answer.
Do you know which size is "the minimum" that can be accepted on Commons?
Thanks a lot for your help!
Warm wishes,
