What is the best way to store user photos?

Question

PHP

I have a site where users can upload their photos, after uploading I make several images from the photo: "photo - original", "photo 300px wide", "square photo" and so on. Before that, it was stored in the img folder, in which there were a couple more folders for different sizes, and photos of all users were uploaded there. Then I read that if there are a lot of photos, the server will slow down. An idea came up: after registration, create a couple of folders for each user specifically for his images. What do you advise? What is the best way to organize all this?

Answer 1

1. You create an array of servers where the photos will be stored
2. You throw a handler for each
3. In the database you store only the path to the folder with the file, for example, like this v311524358/9fc3/Jlgxdu1LABI.jpg and also save the server number.
4. When displaying a photo, you look at the server number, take its path and add the address to the file.
I've done it this way, it's very convenient.

Answer 2

Each user needs their own folder for pictures.

Answer 3

"Then I read that if there are a lot of photos, the server will slow down."
- It will slow down when sorting through files, and there will be no brakes with direct access.
The quickest and easiest option is to name the files according to id_user, id_album and id_photo. And then access the file directly.
