Sort files by last modified date

msbask

This code:
1) Goes through each directory and sub-directory (except those specifically excluded
2) Returns the name of only the .jpg files

What I also need it to do is:
1) Sort the file names by last modified date
2) Only list the 3 (or 4 or 5) newest file names

I'm pretty sure that I need to change the way the file name array is done, but really have no idea where to start.

Any ideas?

Thanks!
