How can you mass rename based on date on a MAC? Let me explain...

[VisualOddity]

Here is the situation for one folder specifically as an example.
I have a folder with pictures I have taken of my son. Said folder has somewhere well over 1700 shots. These all have different names, and I would like to name them w/ a date. Obviously that is far to many to name individually, and I can't do it in a normal bulk rename and have it name them w/ the date in the name. What I would like to do, or is ideal, is to have some sort of an ap that will rename them in mass, but will do it based on the date. For instance: Maybe I could set "Caleb" as a parameter, then it will go down the list and name them like this:
caleb-10-21-07
caleb-10-22-07-01
caleb-10-22-07-02
caleb-10-23-07
caleb-10-27-08
ect...
Does anyone know of a FREE solution to do this? I have lots of folders to do this with, but the ones w/ my kids are the big ones...
Also, I wasn't sure what section to put this in, so if this isn't right, feel free to move it.
And thanks for any help!

In case it matters, the Mac is a:
MacBook
2.4 Core-Duo
Mac OS X 10.5.4
2gb RAM...

I'm pretty sure you can get an automator task to do it (free program already on your mac). You'll have to play around with it a little bit, but I think your answer is in there.

Thanks for the input!
I found a great way to do it a minute ago. Adobe Bridge! Works like a charm! :)

I am glad you found an easy way to do it because otherwise I would probably have spent the next 90 minutes digging up a perl book and debugging then another 30 minutes explaining how to run what I would have written for you.

hahaha! thanks, I appreciate the thought! :)

I find python to be a lot quicker for this type of stuff than perl...

automater for the win, its a few clicks just like bridge.
