1 Corinthians 11:7 (KJV)
7 For a man indeed ought not to cover his head, forasmuch as he is the image and glory of God: but the woman is the glory of the man.
"Cover" here clearly is referring to hair, not a hat.
1 Corinthians 11:14 (KJV)
14 Doth not even nature itself teach you, that, if a man have long hair, it is a shame unto him?
Jesus was/is without sin and would not have covered his head with long hair. Consequently,the image on the shroud cannot be Jesus.
Soooo.... Was Samson a Pagan, got his just desserts from Delilah and by killing his enemies by pushing over the Temple make him a murderer/terrorist? Jes aksin’.
Torah calls for a man to 'poll' his hair - basically anything between short and the length of a fist at the nape of the neck. A proper poll is to gather the hair at the nape and cut it at the outer edge of the fist... Considering discrepancy, shoulder-length may not be considered 'long'. Incidentally, the beard would likely be handled the same way.
