Ooops! I've been organizing image files recently from my camera and realized that I was losing timestamps when moving them to a remote Samba share. Fortunately, image formats and cameras these days are smart enough to embed the original timestamp inside the image itself (assuming you have a moderately recent camera and assuming you've gone thru the process of configuring the date/time).
I hacked up the almost trivial perl script below to touch each file with the data from the exif data.
`#!/usr/bin/perl
jhead $f | grep 'Date/Time'
;touch -t "$d" "$f"
;The script depends on the jhead tool to get the data from the image, but the rest is dead simple.
