Le plus simple est de faire un script nautilus :
http://nawer.freecontrib.org/index.php?2005/06/01/27-script-nautilus-pour-les-images
http://forum.ubuntu-fr.org/viewtopic.php?id=23046

François

Nécessaire : zenity, imagemagick
Glisser le script dans ~/.gnome2/nautilus-scripts/ puis le rendre
exécutable (chmod +x).
