Sounds like we need Rune here...

See his Illusion include file:
http://runevision.com/3d/include/#96

especially section 5.3 of the readme inside:

"5.3   Photo manipulation tool
******************************
If you have a photo, picture, drawing, or whatever, and want to place 
raytraced objects in it, casting the appropriate shadows, then the 
Illusion Include File might be your answer.
Imagine you have a photo of a desktop and you want to place a raytraced 
object on it. First look at the photo as if it were a raytraced picture. 
  Figure out where the desktop is located relative to the light_sources. 
  Try to model the scene. Just make a simple flat box for the desktop 
and add the light_sources. Make sure that the sum of the intensities of 
the light_sources equals to rgb 1. Make a distant plane or very big 
sphere that covers the whole background. Now add the photo to the whole 
scene as an illusion texture. The hard part is to make the photo line up 
correctly with the modeled objects. In the finish of the illusion 
texture use an ambient value that matches the ambient light in the 
photo. Make the sum of the ambient and the diffuse value equal to 1 and 
use brilliance 0.  Now you should be able to place objects on the 
desktop and watch them cast the right shadows."

Maybe this is relevant as well:
