Please could you explain this ?script? a bit more, is it used from the run box windows, or is it mac? Run in Lightroom?
It looks really useful, but I'm a pc user not programmer!
At college my programming instructor concluded I was computer illiterate! Mind you that was when screens were green!

This will rename your files to unique names based on the time the picture was taken. It is very useful when you want to combine files from different cameras, yet have them listed in the order that the pictures were taken.
Replace the .CR2 with .JPG when needed.
I use neither, I use Linux, but you are in luck the exiftool is cross platform, it is a command line tool.

I think there is also a GUI frontend for it.
The renaming of files is just one small part of it, it can do a lot of things to the meta data of pictures.
