[SOLVED] Background instructions need clarification

I am one of those people who, when it comes to following instructions, are limited to what they are literally told. It does no good to tell me, "To get there, turn left at the corner where the school used to be."

Likewise, the instructions on installing a page background require imagination that I lack. Hence my need for something more explicit or expansive on how to install a page background image.

The instructions say,

Well, here is what does not work (taking the instruction literally)

Nor does this (trying to interpret the intention)

nor does:

nor do any of the above work using atahualpa instead of atahualpa3, since the folder is not named atahualpa3, but atahualpa.

and so forth.

Please tell me, literally, what will work and thank you in advance.
