Giam Lumley right? Oh, maybe not... Sorry Liam.

From my very limited understanding of ION, it passes image information
from IDL to the webpage via the Z buffer. If it is possible to use
truecolor in ION generated images I would very much like to hear about
it but I now have acceptable results by adding "cube=6"

read_jpeg, fname, image24bit ;wedding day quality image
image24bit = congrid(image24bit,3,400,400)
loadct, 13
image8bit=Color_Quan(image24bit,1,R,G,B,COLORS=255, cube=6)
TVLCT, r, g, b
TV, image8bit ;image after 25 years of marriage
