Image styles

Problem/Motivation

The solution description in #2793809: [FEATURE] Provide direct download URLs for files and images describes the meta data and derivatives. In the end, what gets committed is just a domain-relative URL that is transferring the stream wrapper to an URI.

What's the current correct way to fetch files with image styles if we have a publicly accessible system, that will not need simple_oauth, consumers and consumers_image_styles module that come from the simple_oauth modue.

Proposed resolution

Have it documented somewhere.

Remaining tasks

User interface changes

API changes

Data model changes

NONE.
