3ds Max :: Putting Custom Background With 2013?

Anyway, I am rendering a car from the game "Nascar Racing 2003" with 3ds Max 2013 64 bit in Mental Ray. I am putting a custom background to the render, however I can not see the background until the render starts. I need to see the background "before" I render so I can place the car in the right place.

I can see the "background/backdrop" before I render the scene? What options do I need to check or un-check? Maybe just the general options for this because that might work for all the renders I do with pictures for backgrounds.
