If you go to https://cs.wikipedia.org/w/index.php?title=Profimann&oldid=19149303, you will see this:
The file called Profiman.jpg is not loaded from Commons, despite it exists at https://commons.wikimedia.org/wiki/File:Profiman.jpg, and globalusage even shows it is used.
This can be reproduced at testwiki, see https://test.wikipedia.org/w/index.php?title=User:Martin_Urbanec/sandbox&oldid=455753.
I'm not sure whether it is a permanent or temporary bug.
Saving a null edit or previewing the page does not help. The file was uploaded at 16:12, 10 November 2020, which should be enough time for the image to propagate.
I cannot reproduce this with a different image so far.
