There's a program called exiftool (and I'm sure many others) that if you say exiftool jpegname.jpg
There's a tool linked in the page above called jhead which allows you to name photos based on EXIF data without needing to do any scripting, I was going to suggest it when I saw the original mail. Currently I use jhead on all my photographs to give them a unique name based on the time+date, image number and the camera used to take them, simply as it's easier to store all the photos in a tree by YYYY/MM.
