Uploads are POSTed to a resource which returns a token which is used to GET

<media>

Clients can get thumbnails by supplying a desired width and height and
thumbnailing method::
=> GET /_matrix/media/r0/thumbnail/<server_name>
/<media-id>?width=<w>&height=<h>&method=<m> HTTP/1.1
<= HTTP/1.1 200 OK
Content-Type: image/jpeg or image/png
<thumbnail>
The thumbnail methods are "crop" and "scale". "scale" tries to return an
image where either the width or the height is smaller than the requested
size. The client should then scale and letterbox the image if it needs to
fit within a given rectangle. "crop" tries to return an image where the
width and height are close to the requested size and the aspect matches
the requested size. The client should scale the image if it needs to fit
within a given rectangle.
