hmmm, don't even want to think about that one

The scenario is this. Going to shoot a small scene of a streetwith a static camera, no movement at all. I have a model of a coin i want to animate rolling down the pavement. The coin is an active rigid body. I thought Maya's live was for tracking sequences of images. whenever i just import a single image it wont track. Anyhow, could i just create a plane and assign the image to that? I'm going to create an establishing shot with a cardboard box on the pavement and i'll have the dimensions of that so i can setup the camera.
