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.

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?

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

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.
