Mine too, so I mark the images I want to look at, using the
window configuration that suits me best at the time, and then use C-t
d. As I use "follow mode", tumme will track the correct thumbnail in
the thumbnail buffer when I go up/down in dired. And the other way
around if I am in thumbnail buffer.

People seem to work very differently. I have several thousand images
in my dir, trying to show them all as thumbnail would not be logical
at all for me, even if the thumbnail creation was asynchronous or similar.

See above. The idea is to keep dired buffer open so that you will see
which thumbnail that matches which file in dired.

I wrote tumme because it did a job I could not find in any other image
viewer. If gimv works for you, good!

You can save a window configuration to a register if you want to,
using `window-configuration-to-register'. Nothing I use myself though.

Can you elaborate? All tumme thumbnail commands work in the thumbnail
buffers, all tumme-commands to be used from dired work in dired and
all commands that should work in the didplay buffer (not many) works
in the display buffer.

You don't have to! Load tumme.el and setup the keybindings by calling
`tumme-setup-dired-keybindings'. Then go to ANY dired buffer with
images. Mark some files and do C-t d. Voila! Thumbnail images
displayed in the thumbnail buffer.

But, the thumbnail buffer is not displayed by default. I created a
experimental command that does, however, which I posted yesterday. Try
binding that to C-t d instead and see if it works better for you.

Yes, and there should also probably be a command that does that for
the user.

Thanks for testing, all comments are valuable! A pity that they come
this late though...
