displaying images inline

[Bernd Wolter]

Hi,

as I wrote in another post I'm running 

GNU Emacs 21.2.1 (i686-pc-cygwin, X toolkit) of 2003-01-23 on DRACO

in a rootless X-Window under Winnt 4 SP 6.

I use this strange setup to be able to display images inline. I have
files that contain strings that point to either tif or gif files in
the same directory or a subdirectory - similar to html files but not
quite.

I do have a special browser and an editor for this kind of file but
both are really very limited and I'd love to use emacs for them.

Now I can insert the images with "M-x insert-image-file" and they are
displayed in all their glory. As soon as I save the file cum image and
kill it the images are replaced by their text representation. How can
I upon re-entry of the file have them displayed as images again? I
tried to add

-*- mode: auto-image-file-mode;-*-

at the top of the file but this doesn't seem to take effect
(auto-image-file-mode is not active), also setting it "by hand" before
visiting the file does not help. The documentation on images is still
a bit sparse to say the least and what I found in the NEWS file on the
display text property left me as clue-less as before.

Is it possible at all? If so how?

Bernd
