Hi, Eric.  Thanks for the information.  Just for the record, I ended up
"cheating" on this problem: I used the ImageMagick utility "montage" to
create, well, a montage of the images I wanted and then just loaded the
resulting, single image.  I've been meaning to close the loop on this but kept
forgetting.
