It shows up in the view window, though. The camera is set to ortho.
Background images do not render, they are used for reference. You could add an image to the World http://wiki.blender.org/index.php/Doc:2.5/Manual/World/Background or map an image to a plane (see the plane as image addon http://wiki.blender.org/index.php/Extensions:2.5/Py/Scripts/Add_Mesh/Planes_from_Images)
