I'm trying to evaluate storage usage on a linux server.

Most of the bulk of storage is coming from the images. I'd like to see if I can get a sense of the size of files modified in the last year. and maybe also the last 5 years, to see how that compares to the total size of the images directory (which is 40GB)

I have tried `du -h` and that is handy, but I cannot see how to filter those results by modified date.
