I'm helping a relative set up a new computer. They've imported all of their photos from the old system to Windows Live Photo Gallery on the new system (running Windows 7), and want the photo's created date to display on the photo (like on their old film-based camera). I've seen tools that can do this one at a time, but this person has over 1000 photos, so I'm looking for a utility that can apply a nice datetime stamp in the corner of the photo in batch mode. I could write code for this, but I was hoping for a faster solution.
(I know that the new digital camera can do this automatically and I have configured that, but I still need to fix the existing photos)
