Send an Image in-line using Python

Referencing the following site I created an HTML email with an image inline.
http://code.activestate.com/recipes/473810-send-an-html-email-with-embedded-image-and-plain-t/

Below is the source code from the above site:

from email.MIMEMultipart import MIMEMultipart
from email.MIMEText import MIMEText
from email.MIMEImage import MIMEImage

strFrom = 'user@domain.com'
strTo = "user@domain.com"

msgRoot = MIMEMultipart('related')
msgRoot['Subject'] = 'Email'
msgRoot['From'] = strFrom
msgRoot['To'] = strTo
msgRoot.preamble = 'This is a multi-part message in MIME format.'

msgAlternative = MIMEMultipart('alternative')
msgRoot.attach(msgAlternative)

msgText = MIMEText('&nbsp;&nbsp;Email Text<br /><br /><img src="cid:image1"><br /><br />Email Text</body></html>', 'html')
msgAlternative.attach(msgText)

fp = open('pic.png', 'rb')
msgImage = MIMEImage(fp.read())
fp.close()

# Define the image's ID as referenced above
msgImage.add_header('Content-ID', '<image1>')
msgRoot.attach(msgImage)

# Send the email (this example assumes SMTP authentication is required)
import smtplib
smtp = smtplib.SMTP()
smtp.connect('mail.server.com')
smtp.sendmail(strFrom, strTo, msgRoot.as_string())
smtp.quit()
