Assuming that all objects are no farther that +100 units along the +z axis and 
that the camera is somewhere back along the same axis and looking toward +z.
With comments:

box{<1000,1000,100><-1000,-1000,101> // a large box
	image_map{gif "your gif.gif" // place the image from 0,0 to 1,1
		translate<-0.5,-0.5,0>// center it around the z axis
		scale<2000,2000,1> // stretch it to cover the whole box.
//adjust the scale values as needed
		}
	finish{ambient 1 // make it fully illuminated
		diffuse 0} // independent of actual illumination, don't catch shadows
	}
Obviously, if your image is not square, you need to change the scaling factor to 
equal it's original proportions.
