What is the ideology of uploading files when working with the REST API?

Question

RESTful API

Let's say we have a RESTful API and we're editing a user entity.
If I want to change the user's avatar, how should the interaction with the API be ideologically correct?
One PUT/PATCH request per /user with image transfer? - after all, we are changing the essence of the user.
or
two requests. First POST to create a picture, then POST / PATCH to change the user and bind a new avatar to him?
The second option seems to me more REST, but it involves two ajax requests instead of one.

Answer 1

Can't you send a POST to something like /user/:id/logo?
