Fix time-stamped filenames of JPEG images according to the EXIF date the photo was taken
For each *.jpg or *.JPG file in the current directory, extract the date the photo was taken from its EXIF metadata.

A trick from https://unix.stackexchange.com/a/9256 is used to split the date into its components.
