Download exif-to-date version 1

Exif to date is a simple Nautilus script that takes a bunch of images and resets their modification date to the one corresponding to the EXIF tag.

If you're a Debian/Ubuntu user, just install the package (then enable the script with System → Preferences → Nautilus Scripts Manager).

Otherwise, download the script above to /home/yourusername/.gnome2/nautilus-scripts and make it executable.
