How to add the images in smtp mail body

To add images to the body of an SMTP email, you'll need to use a combination of HTML and base64 encoding. Here's a step-by-step guide:

Step 1: Convert the image to base64

Use a tool like base64 command-line utility or an online converter to encode the image file into a base64 string. For example:

base64 -i image.jpg

This will output a long string of characters that represents the image data.

Step 2: Create the HTML email body

Create an HTML file that contains the email body and the image. For example:

<html>
  <body>
    <img src="data:image/jpeg;base64,[base64_encoded_image_string]" alt="Image">
  </body>
</html>

Replace [base64_encoded_image_string] with the actual base64 encoded string from Step 1.

Step 3: Set the email content type

When sending the email, set the Content-Type header to text/html to indicate that the email body is in HTML format.

Step 4: Send the email

Use your preferred SMTP library or tool to send the email. For example, in Python using the smtplib library:

import smtplib
from email.mime.text import MIMEText

msg = MIMEText(open('email_body.html', 'r').read())
msg['Subject'] = 'Test Email with Image'
msg['From'] = '[email protected]'
msg['To'] = '[email protected]'

server = smtplib.SMTP('smtp.example.com')
server.sendmail('[email protected]', '[email protected]', msg.as_string())
server.quit()

Make sure to replace the placeholders with your actual email credentials and settings.
