in reply to Change Image File Timestamp to Match EXIF Data
Nifty tool, I was going to write one myself, but a quick search found this.
I ran this on a copied subtree of photos of my young daughter - I wrote a perl script to extract all my files from flickr as I'm making my own gallery now.
This script complained a lot with warnings, but it did do exactly what I needed first go to all images that had Exif data (I processed some wayback before I knew to preserve the exif data in gimp).
I would call it quick and dirty, its exactly what perl does best.
