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 = ""
