Technical Summary
This document describes the usage of the 'image' media type
and registers it with IANA as a top-level media type for the
Session Description Protocol (SDP). This media type is
primarily used by SDP to negotiate and establish T.38 media
streams.
Working Group Summary
While this is not an official document of the MMUSIC working
group, the document has been reviewed in the MMUSIC WG. It is
widely supported by its members and external bodies. Has
received substantial review, including an unofficial
WGLC. There is consensus to proceed forward with the
document. Since this document is registering a missing token
in an existing registry, it was decided to expedite the
document in the sake of simplicity and speedness.
Document Quality
There are implementations and RFCs documenting the usage of
the "image" media type in SDP. This document adds it to the
SDP parameters registry.

RFC Editor's Note:
OLD:
The 'image' media type for the Session Description Protocol
is used to describes a media stream that represents a still
image. The media subtype further describes the specific
format of the image. Currently, the 'image' media type for
SDP is used ubiquitously by the SIP control protocol to
establish T.38 media streams.
NEW:
The 'image' media type for the Session Description Protocol
is used to describe a media stream whose content consists of
one or more separate images that require appropriate hardware to
display. The media subtype further describes the specific format
of the image. Currently, the 'image' media type for SDP is used
ubiquitously by the SIP control protocol to establish T.38 media streams.
