The beauty of Max is there is always more than one way to do something

Max has a Viewport display option setup that kinda goes like this:
Select Front viewport
Display Background
File: browse and <select image>
Match Bitmap
Lock pan and zoom
Or .. the way I did it

I mapped a planar object with UV coordinates
match bitmap selected and scaled for fit
Applied the front face shot to it as a diffuse color bitmap
Went to object properties and turned off 'receieve shadows'
Same for side view.
Same way I do a plane, etc.
A good template makes it easier by far.
You can flip thru the views without worrying about 'losing' or fighting with your front background view,
full screen viewport all the way, even perspective views.. no problem.
