Chapter 6 of the CookBook is all about displays.  You can make a
printer version of the image with PRTIM.  Contours are done by many
tasks - the simplest is CNTR, but GREYS, PCNTR, and KNTR offer more
options.  In a current 31DEC06 the latter 2 even allow color contours
and all 3 allow grey scale as well as contour.  E.g. you could do one
of the two images in grey scale and the spectral index in contour or
vice versa.  The plots may go to the TV directly or to a file.  In the
latter case, LWPLA converts the plot file into a PostScript file which
may be save on disk or printed directly.
