Here is how I would display all 57 of the 80-by-100 images
in the head.dat data set:
file = Filepath(Subdir=['examples', 'data'], 'head.dat')
OpenR, lun, file, /Get_Lun
data = Bytarr(80,100,57)
ReadU, lun, data
Free_Lun, lun
Window, XSize=80*10, YSize=6*100
FOR j=0,56 DO TV, data[*,*,j], j
Cheers,
David

Hi,
This is pretty easy if you get on of the right tools. Both David
Fanning's TVIMAGE (and TVSCALE) and Liam Gumley's IMDISP will honor the
!P.MULTI system variable which you can set up to display individual
plotting regions in a grid layout. Each of these will honor the POSITION
keyword if you want to carve up the display space on your own. The
documentation for IMDISP has an example of how these work.
