How to correctly name files with modifiers and the same names?

Question

Data storage

In my case, the question is about storing files in storage like S3.

There is a conditional image.jpg file .
When loading through an interlayer, I have reduced copies of the file, conditional small , medium .
How to name these files?
I have a bem naming methodology in my head: image_small.jpg , image_medium.jpg .
But I also saw that they put the modifier in front: small_image.jpg , medium_image.jpg .
Is there any purpose to this other than "I'm so comfortable"?

The files can also have the same name. In this case, some hash is added:image_small_0d2e2011dc.jpg , image_medium_0d2e2011dc.jpg .
By what rule to generate this hash?

The only question is whether there are specific recommendations in such cases or not. Since I am just starting to understand this direction, I want to initially use some kind of standard (even if it is imposed by some top company). Or at least try to learn more about it.

I want to use some standard from the beginning

There is no such standard. Smart books write about data structures. What you're asking about is a file naming plan - it's also a data structure in some way.
The data structure is made for a specific task. At you the specific task is not described, a question in the general form.
