To automatically clean the thumbnails generated by Nautilus, and who never get cleaned by GNOME itself and can really fast occupy a large part of your disk space, I setup a cronjob like this in /etc/cron.d/clean-gnome-thumbnails on my Debian:
#
# Clean GNOME thumbnails files
#
# Every day, at 22h.
0 22 * * * root find /home/*/.thumbnails/ -type f -atime +90 -exec rm {} ;
This cronjob would remove thumbnails older than 90
