我的目标是使用Python向具有内嵌图像的Gmail用户发送电子邮件.href由于图像的敏感性(来自我工作的数据),无法在线托管此图像然后通过a链接到该图像.

我已经尝试将该base64版本编码为HTML然后发送HTML,但众所周知,这不起作用.然后我注意到,在Gmail中,您可以将图像拖放到发送框中,它将在接收端显示为内联.鉴于此,我尝试从Python发送一封电子邮件,并将图像作为附件.这可以在下面的代码中看到,但不幸的是图像没有显示为内联.

我的问题是:如何发送图像使其显示为内联？

import smtplib
from email.MIMEMultipart import MIMEMultipart
from email.MIMEBase import MIMEBase
from email.MIMEText import MIMEText
from email import Encoders
import os

gmail_user = "user1@gmail.com"
gmail_pwd = "pass"

to = "user2@gmail.com"
subject = "Report"
text = "Picture report"
attach = 'TESTING.png'

msg = MIMEMultipart()

msg['From'] = gmail_user
msg['To'] = to
msg['Subject'] = subject

msg.attach(MIMEText(text))

part = MIMEBase('application', 'octet-stream')
part.set_payload(open(attach, 'rb').read())
Encoders.encode_base64(part)
part.add_header('Content-Disposition',
   'attachment; filename="%s"' % os.path.basename(attach))
msg.attach(part)

mailServer = smtplib.SMTP("smtp.gmail.com", …
