While 256x256 is a good choice for cache reasons,
there should be no principle difficulty to increase this
to 512x512 (or even to 1024x1024 if the machine is fast enough).
But (and that's a pretty big "but"): the thumnails are stored in
~/.thumbnails/large and the freedesktop thumbnail standard
is 256x256 for this. So increasing this would break this.
Moreover, this will lead to quite a bit of disk space usage
in this directory...

However, I do understand the wish!
Maybe there is some other approach which could be done
(eg. using the cached version first, but then display
a refined variant internally? This is to some extent
related to http://bugs.kde.org/show_bug.cgi?id=146260)?

Best, Arnd
