SVG currently doesn't work; using .jpg instead

[MikeTheGreat]

Summary of the Pull Request

Docs show example config with with a background image
That image is listed as being .SVG
SVG currently doesn't work
Let's have the docs use .jpg instead

Since the JPG won't stretch nicely we're also going to put it in the top-right corner without any scaling

We can go back to an SVG file after #2441 gets fixed

I personally prefer pngs over jpgs. Pngs are typically better quality images though that doesn't have to be the case. Did you ever check if the stretching works for png vice jpg?

[MikeTheGreat]

I, too, prefer .PNGs (because of the transparent backgrounds) :) I left the .JPG in the docs to minimize changes.

The stretching DID work for .JPG. It looked horrible (my window size was way bigger than the image) but it worked.

Transparent .PNGs in the top-right corner for the win!
