That might be the "best way" for you, but not for everyone. Personally I have so many pictures that I really appreciate the "memories" that Apple Photos extracts and shows me from time to time. That would be very hard to implement yourself. It always picks good pictures and not random screenshots you have lying around or blurry pictures. A directy listning is definitly not a scalable solution if you are not looking to just go through all pictures of a specific date.
