The date has been discredited and one would expect the original researches to deny they made a mistake. It is now accepted by creditable researchers the original dating was in wrong due to a sampling error.<quoted text>
And how was the carbon dating discredited? There has been a claim that the sample was taken from a medieval 'repair', but the original researchers deny that as a possibility.
Whether the image is from an artist (by far the most likely case) or a corpse (also possible; but a medieval, one if so) is irrelevant if the age is less than 1000 years.
Once again, without further samples being taken and analyzed, it is impossible to go further.
Which is it: An image of a corpse or a painting? Now remember this is the 21st century with 21st century forensics. Are you telling me forensics cannot tell the difference? Do some research and give me a definitive answer.
