How to send HTML email with inline attached image using PHP

I have a PHP script that sends an HTML email with an attached image. This works great, but I can’t get the application to appear in the tag <img>in the body of the message. The attached file is called postcard.png, and the original file name on the server is 4e60348f83f2f.png. I have tried to indicate URL-address of the image as a different thing: cid:postcard.png, cid:4e60348f83f2f.png, postcard.pngand 4e60348f83f2f.png. Nothing works.

I think the key part that I am doing wrong is here because it makes it a split attachment instead of the inline application that I can use:

Content-Transfer-Encoding: base64
Content-Disposition: attachment;
    filename="$fname" // i.e.: "postcard.png"

I tried changing it to use CID, but I really don't know how to do this, and this did not work at all:

Content-Transfer-Encoding: base64
Content-ID: <$fname> // i.e.: postcard.png

: ( php mail().)

<?php
$to      = "recipient@email.com";
$email   = "sender@email.com";
$name    = "Namename";
$subject = "An inline image!";

$To          = strip_tags($to);

$HTMLMessage =nl2br($comment);
$FromName    =strip_tags($name);
