http://www.npbmto.gov.tw/NPBO_C/Web/Data/Board/456-4.tif has seven parts,
$ identify 456-4.tif
456-4.tif[0]
456-4.tif[1]...
but using image-mode, one would never see or know more than the first.

I've added the same support that we currently have for multi-image GIF 
files to the TIFF support in CVS trunk.

This doesn't really help the user discover that multiple images exist, 
and there isn't currently a convenient way for non-programmers to select 
such subimages for display, so I'm leaving this open as a wishlist for now.

The file above contains 7 images but image-extension-data returns
(count 8).

I can't find information about how to display (in Elisp) the
various images.  Could someone clue me in as to where to find that info
(etc/NEWS or Elisp manual) or if it's not there, could someone add
it there?

Is the node "Images" (in display.texi) and its subsection what you are
looking for?

Oh, I see it's in Gif and Tiff, rather than in the generic section.
It should probably be moved to the generic section with a note about the
fact that it can only apply to Gif and Tiff (as of now).

In the elisp manual there is an existing description of the :index 
property for GIF images. That description now also applies to TIFF. 
There isn't currently a user-level method of displaying these.
