Hi Joakim,

I have tried your layout and you're right that this is annoying: for me
the dired buffer and image view buffer are switching windows each time I
go to the next image.

Maybe we should try to fix this but, as usual, with Emacs display layout
it could not be to everybody's taste.

Thanks for this hint.  You're right that the kill/pop-to/rename dance
may be the cause of this issue.
