You could also try this simple 'three nested boxes' idea. The trick is that each
box is *very slightly* larger or smaller, so that the image_map applied to each
one appears only on the desired surfaces. Any 'streaking' is actually hidden
inside the slightly larger boxes.

// all three boxes centered on origin:
union{
box{0,1 // for FRONT and REAR
 pigment{image_map{jpeg "MY_IMAGE_1.jpg" interpolate 2}}
 translate <-.5,0,-.5>
 }
box{0,1 // for TWO SIDES
 scale <.999,.999,1.001>
 pigment{image_map{jpeg "MY_IMAGE_2.jpg" interpolate 2}}
 translate <-.5*.999,0,-.5*1.001>
 rotate 90*y
 }
box{0,1 // for TOP
 scale <.998,1.001,.998>
 pigment{bumps scale .01}
 translate <-.5*.998,0,-.5*.998>
 }
 }
