The email MIME stuff is not really adapted for HTTP. I would advise to
use the Requests package (http://docs.python-requests.org/en/latest/) or
the Uploading Files part from Doug Hellmann's page
(http://doughellmann.com/2009/07/pymotw-urllib2-library-for-opening-urls.html).
This is for Python2; I can send you a Python3 version if you want.
