send email html content with inline image

• preferred way:
• script to generate html content with image encoded as base64 text
• <img src='data:imag/png;base64,....'/>
• base64.b64encode().decode("ascii") to get that ... string from image
• single html file to include all the html and images, etc. 😀
• cat that html and pipe to mutt -e "set content_type=text/html" to send the email

• however, outlook does not support inline base64 image 😞
• one way to workaround is to pipe the html to a python script that
• extract that base64 string (... above)
• replace html code with <img src='cid:123' />
• create image object with
• image = MIMEImage(base64.decodebytes(....encode("ascii")), _subtype=<png/jpg/etc>)
• reference this image by
• image.add_header('Content-ID', '<123>')
• send the emails as shown in this example

• To send from windows outlook client rather than directly via smtp server:
