Actually, the shrouds image is not a very big mystery at all. It actually is more likely to show it being a fake than not.
For example, it does not show the distortion that a 3-D image would make. It can be reproduced easily by taking a 2-d wood carving, placing
a cloth over it, and then brushing the highlights.
Of course, the biggest thing about the shroud of Turin being fake is how the shroud does not match how people were buried in the 1st century, but rather how people were wrapped up starting in medieval times. That, and the testimony of the Bishop who aquired it to begin with.
It also contradicts the bible. The weave of the cloth does not match how they made cloth in the 1st century. The 'blood' had no matting, and it has not properties of blood. There is no trace of the 100 pounds of spices that the Gospel of John claims he was buried with.
That is above and beyond the C-14 dating.
