I was starting a graphic and I wanted to use a photograph that I converted
into a GIF. How is it possible to make a Gif into a background and put a
metal sphere or another object into the foreground making it look like the
GIF in the background all fits together realistically, so it looks like all
one picture. Appreciate your attention.               Brian

The concept of a background image is not supported in Pov-Ray, but you can
create a screen (cube) and use an image_map to project a bit-mapped image
on it. Then you can place your sphere in front of it.
See 3.5.1.5.1  Specifying an Image Map

Place a large box behind all objects in your scene.
Apply your image as an image_map. Scale it to fit. The image start as an 1*1 tile.
Give it finish{ambient 1 diffuse 0} to prevent it from catching shadows. This 
makes it ignore all light in the scene and be visible.

Thank You, Alain. How would this look typed on the POV program itself?
Please Help. I need a book named POV for dummies.

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.
