This case is fairly simple.  The Jpeg codec does not encode/decode
"binaries", it handles abstract "images".  (In fact, it's a strict
subset of "images", namely, images with three 8-bit channels, where
the channels represent RGB space or something else easily converted to

I'm still not convinced that Codec.Image makes sense in isolation from
a representation of "images".  It's hard to see what you'd do with such
a library without some other image handling stuff.
