Ok, Raff may be you have more experience 
Let’s suppose you have > 1000 pictures in your e-shop.
How you can organize it in existing Media Library (and describe it to content manager)?
From time to time you will need to change photos for some goods and some good’s group can share some photos.
What’s will be the best way to organize photos ?
I’m use windows 10 and the best photo organization photo software is https://www.acdsee.com/ (IMHO)
In short it has:
- folder - provide by Windows 10
- tags
To realize tags - you have to add to Media Libarary only one text field - or special “tag” field (to separate tags) - like stackoverflow.com
Exist Alternative text and Caption fields is used for SEO purposes.
If tags field will be available in Media library - it will cover folder future
