Yes, I was confused about this. Mea culpa.

So really people should only be linking to and from zones generally.

I've known ppl to do stranger things.

Yup I was confused.

Ok, and if those graphic/@coords are relative to the surface, how do we on the
surface indicate what unit of measurement they are using? Surely a surface may
be measured in all sorts of units (millimetres, inches, metres,
kilometres,etc.)? How do I know that one graphic is higher resolution than the
other? i.e. they both cover the same area of the surface "0 0 100 100" but one
was taken with a hi-res camera, and one was taken quite awhile ago with some
low-res camera. How is that resolution indicated?

Yes, greatly. Don't think I've got it entirely.
