Images and binary content are usually send as ASCII characters. Weird eh?

Here's what Wikipedia has to say about the MIME standard:
http://en.wikipedia.org/wiki/MIME

RFC 822:
http://www.ietf.org/rfc/rfc822.txt

You can try it yourself. Send an image using email then look at the message 
source. The binary image file has been converted to ASCII characters.

Cheers,
Chris
