I don't think he meant a bead per pixel, just a single color for each 
bead. In MegaPOV, you could use the eval_pigment() patch to get the 
color of the image_map at the center of each bead. With the official 
version, you would have to either code a program to get the needed 
information, or just translate the texture so the portion at the bead 
position is at < 0, 0, 0>, scale it large enough that you can't see any 
color blend across it, then translate it to the bead position.

object {Bead
    texture {ImageTexture
        translate -BeadPosition
        scale 100// this should be big enough...
    }
    translate BeadPosition
}
