xrange = [-5, 5]
yrange = [5, 15]
image = Dist(256)
LoadCT, 33, NColors=100, Bottom=1, /Silent
position = [0.1, 0.1, 0.9, 0.75]
TVImage, BytScl(image, Top=99), Position=position, $
/Keep_Aspect, /Erase, /NoInterpolate
Plot, xrange, yrange, XRANGE=xrange, YRANGE=yrange, $
Position=position, XStyle=1, YStyle=1, /NoData, /NoErase
Colorbar, Range=[Min(image), Max(image)], Divisions=10, $
Minor=5, NColors=100, Bottom=1, $
Position=[position[0], 0.88, position[2], 0.95]

You could easily slap this into a wrapper procedure if you
like. Call it IMAGESC. :-)

You can find the relevant programs in the Coyote Library.
