**UPDATE**:
The darkened Area behind the Bio on the Image File is no longer necessary.

Inbetween of the Header Image and the Bio, Instead of a slightly darkened Background, that's still too light to make the Text readable, in most Cases,

there's now a very dark, but good-looking Drop Shadow instead,
that does a excellent Job of making the Bio clearly readable, even on the lightest of Backgrounds.

So a darkened Background for the Bio integrated in the Header Image
is no longer necessary.
