Removing the Viewport Background Image

Today, someone asked me how to get rid of a reference to a bitmap that was put in the viewport background and I thought "Yea, I know this.  Its a quick script line where you reset the filename to an empty text string "".  

However, I once again cant remember the exact variable that i have to reset.  imageviewportbackgroundfilename?  Soooo, after looking it up again, I'm posting it here spo I can always just come back and look it up.  I should do that more with things I always forget...

BackgroundImageFilename = ""

can't you just do ALT+B and uncheck it?

That will turn it off, but that scene will always reference that image. It's more annoying than a real problem.
