python - Embed picture in email

11
votes

I currently have a program that will randomly select quotes from a list and email them. I'm now trying to embed an image in the email as well. I've come across a problem where I can attach the email but my quotes no longer work. I have researched online and the solutions are not working for me. Note that I am using Python 3.2.2.

Any guidance would be appreciated.

import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.image import MIMEImage

attachment = 'bob.jpg' 

msg = MIMEMultipart()
msg["To"] = to_addr
msg["From"] = from_addr
msg["Subject"] = subject_header

#msgText = MIMEText(<b>%s</b><br><img src="cid:bob.jpg"><br>, 'html') % body

fp = open(attachment, 'rb')
img = MIMEImage(fp.read())
fp.close()

msg.attach(img)

#email_message = '%s\n%s\n%s' % (subject_header, body, img)
email_message = '%s\n%s' % (subject_header, body)

emailRezi = smtplib.SMTP(mail_server, mail_server_port)
emailRezi.set_debuglevel(1)
emailRezi.login(mail_username, mail_password)
emailRezi.sendmail(from_addr, to_addr, email_message)
#emailRezi.sendmail(from_addr, to_addr, msg.as_string())
emailRezi.quit()

As you can tell from the code above I've tried different ways (referencing the #)

since emails are almost always displayed in HTML nowadays including an image is not the problem, but whether the end user will see it or not is another matter because they are almost always blocked unless specified otherwise - Tules
Please post the code you are using. - cdeszaq

You are going through royal pains to construct a valid MIME message in msg, then ditching it and sending a simple string email_message instead.

You should probably begin by understanding what the proper MIME structure looks like. A multipart message by itself has no contents at all, you have to add a text part if you want a text part.

The following is an edit of your script with the missing pieces added. I have not attempted to send the resulting message.

from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText  # Added
from email.mime.image import MIMEImage

attachment = 'bob.jpg'

msg = MIMEMultipart()
msg["To"] = to
msg["From"] = from
msg["Subject"] = subject

msgText = MIMEText('<b>%s</b><br><img src="cid:%s"><br>' % (body, attachment), 'html')  
msg.attach(msgText)   # Added, and edited the previous line

fp = open(attachment, 'rb')                                                    
img = MIMEImage(fp.read())
fp.close()
img.add_header('Content-ID', '<{}>'.format(attachment))
msg.attach(img)

print msg.as_string()
exit(0)

I have edited for attaching the image on a message body and HTML template.

import smtplib
from email import encoders
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.mime.base import MIMEBase
from email.mime.image import MIMEImage

strFrom = '[email protected]'
strTo = '[email protected]'

# Create the root message 

msgRoot = MIMEMultipart('related')
msgRoot['Subject'] = 'test message'
msgRoot['From'] = strFrom
msgRoot['To'] = strTo
msgRoot['Cc'] =cc
msgRoot.preamble = 'Multi-part message in MIME format.'

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

msgText = MIMEText('Alternative plain text message.')
msgAlternative.attach(msgText)

msgText = MIMEText('<b>Some <i>HTML</i> text</b> and an image.<br><img src="cid:image1"><br>KPI-DATA!', 'html')
msgAlternative.attach(msgText)

#Attach Image 
fp = open('test.png', 'rb') #Read image 
msgImage = MIMEImage(fp.read())
fp.close()

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

import smtplib
smtp = smtplib.SMTP()
smtp.connect('smtp.gmail.com') #SMTp Server Details
smtp.login('exampleuser', 'examplepass') #Username and Password of Account
smtp.sendmail(strFrom, strTo, msgRoot.as_string())
smtp.quit()
