There seems to be interest in a non-repeating version of this BB Code, so, here's one I've just coded to complement the one announced earlier, the BGN code. It works exactly as the BGN code except that the image displays once and doesn't repeat.
Using the same example, with the the Eratosphere image as background, we have:
Code:
[bgn="http://www.ablemuse.com/erato/images/visioncollison/misc/header.gif"]background image example[/bgn]
.
Which renders as follows:

These details can also be found in the site FAQ function, BB Code section,
here.
