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,
As others say, 2 Mpixels should be the minimum resolution, although it is a bit small to do any work (i.e. restoration). That's the minimum requirement for quality and featured images on Commons.
For doing restoration, it is quite comfortable around 12 Mpixels (4000 x 3000). That's what most cameras offer today.
geograph's 640 × 480 is the lowest widely used resolution.
Any that small resolution should be refused nowadays.
Regards,
Yann
