Before we decide any "drastic" solution like The Big Merge, please
consider the small additions and changes from my last couple of posts.

I see. Another configuration that I set up manually sometimes, is
this:

 
 +--------------+
 |     D        |
 +------+-------+
 | TB   |  DB   |
 |      |       |
 +------+-------+
                
D = dired
TM = thumbnail buffer
DB = display buffer

It has the advantage of not truncating the dired information.

I understand.

I like the idea but I'm not sure I would manage buliding such a beast
:)

No, it's not. :)

Correct, but the new command I posted earlier in this thread
does. Check it out.

The sized image is stored using the file name in variable
`tumme-temp-image-file'. So you could copy that file to a new one, but
it would be better to provide such a command in the display buffer
instead.

I noticed that box today too and then it was because Emacs does not
handle the image file type. What `f' does, although it just says
"display in full size bla bla) is really to just let Emacs try and
display the file. This could be fixed by converting the full size
original to a full size jpeg (which is what tumme always converts to),
but I am not sure that feels good.

Hmm, I will try to recreate that, thanks!

No no. Don't move to the *tumme* buffer before running that command
(C-t d), run it from the Dired buffer. That should work much much
better! :)

Ah, good!

Now read my earlier posts too :)
