Well, clearly you are going to have to do it in a loop. :-)

You can gather all the files in a directory with File_Search,
figure out how many there are (keyword to File_Search), and
loop through them 8 at a time.

I would display them differently though. I would display
8 files like this:

!P.Multi=[0,4,2]
LoadCT, 0, /Silent
Device, Decomposed=0
Erase, Color=255
FOR j=0,7 DO BEGIN
; read the image file and get the image on this line
TVImage, image
ENDFOR
!P.Multi = 0

Cheers,

David
