With that cuboid image you have, you could take the average pixel intensity 
over each face (in the x y and z direction), then assuming the texture was 
the same on each face you'd have an approximation of the light intensity on 
each face.  You should be able to then determine the direction the light is 
coming from, and a guess at the light intensity (you can't know for sure, 
since you don't have the original texture used on the surface).
