  How to compose MIME message in MIME-Edit mode.

  C-c C-x ? shows its help.

C-c C-x C-t	insert a text message.
C-c C-x TAB	insert a (binary) file.
C-c C-x C-e	insert a reference to external body.
C-c C-x C-v	insert a voice message.
C-c C-x C-y	insert a mail or news message.
C-c C-x RET	insert a mail message.
C-c C-x C-s	insert a signature file at end.
C-c C-x t	insert a new MIME tag.
C-c C-m C-a	enclose as multipart/alternative.
C-c C-m C-p	enclose as multipart/parallel.
C-c C-m C-m	enclose as multipart/mixed.
C-c C-m C-d	enclose as multipart/digest.
C-c C-m C-s	enclose as PGP signed.
C-c C-m C-e	enclose as PGP encrypted.
C-c C-x C-k	insert PGP public key.
C-c C-x p	preview editing MIME message.
...

therefore, you should type C-c C-x C-i and specify the binary file
which you want to insert.

  You should select Base64 as MIME encoding for binary file.
