Further to my previous attempts to convert RAW files to Jpeg, here’s a Nautilus script based on this script. How do you use it? The g-scripts FAQ has more, although in Ubuntu I had to copy the script into ~/.gnome2/nautilus-scripts/
This script uses “Zenity” to display a nice progress bar while the conversion takes place.
(while [ $# -gt 0 ]; do
dcraw -c -a -n -h $1 | ppmtojpeg > `basename $1 cr2`jpg
done) | zenity --progress --pulsate --text "Converting RAW files to Jpeg"
