How to add images premission email header for gmail mail

To add an image permission email header for Gmail mail, you can use the Disposition-Notification-To and Content-Type headers. Here's an example:

Example Email Header:

From: Your Name <[email protected]>
To: Recipient's Email <[email protected]>
Subject: Image Permission Request

Disposition-Notification-To: [email protected]
Content-Type: multipart/related; boundary="----boundary_string----"

----boundary_string----
Content-Type: text/plain; charset=UTF-8

Please confirm that you permit the inclusion of images in this email.

----boundary_string----
Content-Type: image/jpeg; name="image.jpg"
Content-Disposition: inline; filename="image.jpg"

[Insert the image data here]

----boundary_string----

Explanation:

• Disposition-Notification-To: specifies the email address that should receive a notification when the recipient views the email.
• Content-Type: specifies the type of content in the email. In this case, we're using multipart/related to indicate that the email contains multiple parts, including a text part and an image part.
• boundary: specifies the boundary string that separates the different parts of the email. You can choose any unique string for this purpose.
• Content-Type for the text part: specifies the type of content as plain text.
• Content-Type for the image part: specifies the type of content as JPEG image.
• Content-Disposition: specifies how the image should be displayed. In this case, we're using inline to display the image directly in the email.

Tips:

• Make sure to replace [email protected], [email protected], and image.jpg with your actual email addresses and image file name.
• You can use any image file format (e.g., PNG, GIF, BMP) instead of JPEG.
• If you're using a programming language to send the email, you may need to encode the image data and add the necessary headers manually.
• Gmail may strip or modify the email headers, so it's essential to test the email in different email clients to ensure it works as expected.
