Would this just-recently-declassified snippet help?

vol = dblarr(100,100,20)  ; 100x100 images, 20 of them
for i = 0, 19 do $
  vol(*,*,i) = read_my_image(image_file(i))

Extra bonus points can be gotten for recognizing the speed-up achieved
by saying "vol(0,0,i) = " instead.

Somehow I think you are asking for more though?
