What is the use of MIME within message makeup?

Answer:

MIME message includes the picture stored as file in GIF format and the GIF format uses 8-bit format. The RFC 822 uses ASCII text format. The messages in the form of ASCII text format is to be encoded. To display the image in the recipient system, the information abut the encoding mechanism is used. The message is to be made up in the recipient’s application. The following snippet is used to identify the content is a GIF file which is to be encoded using the standard “base64Algorithm. This is to be treated as an attachment by the client who uses the email.

Content-Type: image/gif;
name="waterfall.gif"
Content-Transfer-Encoding: base64
Content-Disposition: attachment;
filename="waterfall.gif"
[Author the encoded content here]
..
