MIME media type name : image

MIME subtype name : IETF Tree - jpeg

Required parameters : None

Optional parameters : None

Encoding considerations :
 
Image/jpeg objects consist of binary data.  A content-transfer-encoding of
"Binary" is strongly encouraged for messaging environments which
support binary transport.  A content-transfer-encoding of Base64 (and
the associated transformation) is strongly encouraged for messaging
environments that do not support binary transfer.

Security considerations :
 
(1) Image/jpeg objects contain only "passive" binary data.  There is
    no active executable content.

(2) Image/jpeg objects are not signed or encrypted internally. External
    security mechanisms must be employed to ensure content confidentiality and
    integrity.

Interoperability considerations :  None
