Image upload error in 3D warehouse : 'File format is not allowed'

it could be a chrome-related issue, I tried in SU, same error, while on firefox, it’s all clear.

And then I remembered having issues with JPG a few years ago, solved by renaming them jpg

So I tried. PNG in capital letters is refused, but simply renaming it png works.
