Describe one image stream (file). Its name, for purposes of display,
is 'name'. The file is open as *fileP and positioned to the beginning.
'allimages' means report on every image in the stream and read all of
every image from it, as opposed to reading just the header of the first
image and reporting just on that.
'justCount' means don't tell anything about the stream except how
many images are in it. Pretty useless without 'allimages'.
'wantComments' means to show the comments from the image header.
Meaningless with 'justCount'.
