  63 %  DisplayImageCommand() displays a sequence of images on any workstation
  64 %  display running an X server.  Display first determines the hardware
  65 %  capabilities of the workstation. If the number of unique colors in an image
  66 %  is less than or equal to the number the workstation can support, the image
  67 %  is displayed in an X window. Otherwise the number of colors in the image is
  68 %  first reduced to match the color resolution of the workstation before it is
  69 %  displayed.
  70 %
  71 %  This means that a continuous-tone 24 bits/pixel image can display on a 8
  72 %  bit pseudo-color device or monochrome device. In most instances the reduced
  73 %  color image closely resembles the original. Alternatively, a monochrome or
  74 %  pseudo-color image sequence can display on a continuous-tone 24 bits/pixels
  75 %  device.
  76 %
  77 %  The format of the DisplayImageCommand method is:
