Organization of storage of photos of the goods of the online store?

Question

Online shopping

Good afternoon.
It's not entirely clear to me how to store this whole thing, do I need to store a lot of photos of different sizes, how to structure a catalog, how to call photos names to avoid collisions?
For example, there are 10,000 products, if you create a catalog for each photo size, you will get 3-4 catalogs with 10,000 files inside, there will be a load on the file system .. or create a separate catalog for each product, but then there will be 10,000 product catalogs in the main catalog ...

Answer 1

Store the original as you like, preferably without Cyrillic, spaces and hyphens, in an optimized state
Use <img width="" height="">c https://developers.google.com/speed/pagespeed/module/
If you need to view images through the gui, scatter everything in directories of 1000 pieces each

Answer 2

1) Store files with a hash name of the form 0b6ac707bc62fe8b4afb1cc8a1bc72cf.jpg
2) To avoid many files in one directory - store in directories in parts of the file name
3) Store the real file name that was when uploading.
4) Cache resizes, for example:

/resize_cache/0b6/ac7/07b/100x100/0b6ac707bc62fe8b4afb1cc8a1bc72cf.jpg
/resize_cache/0b6/ac7/07b/650x650/0b6ac707bc62fe8b4afb1cc8a1bc72cf.jpg

UPD: It's also great to store other data in addition to the original name at the time of upload:
1) Height
2) Width
3) File size
4) MIME type
5) File description

Answer 3

Не хочу показаться КО, но на сайт можно вывести одну и ту же картинку в разном размере. HTML позволяет это делать.

Answer 4

Немного отсебятины:
У себя файлы храним в каталогах по 1000 шт., полет нормальный.
Обязательно создаем превью файла меньшего размера, пользуемся именованием фликера, т.е. в конце файла ставим _s для тумбов.
Названия берем из алиаса + микротайм, например: kvartira_v_belitsah_27535.jpg, kvartira_v_belitsah_27535_s.jpg
