Ask HN: How do you (or your parents) organize family photos?

Juts had this problem:

My mom: "I want to go through all our family photos and select few photos to print and make a physical album."

Currently, our family photos are scattered across our phones, digital cameras, and old backup dropbox account I made few years back.

Is there a good way for her to somehow go through all those photos and somehow sort them?

(my mom is not tech savvy. she doesn't know how to close a tab on a browser. that concept just goes over her head. so does the concept of filesystem, or file/directory for that matter.)
