Embedding images into email body

What's wrong with my php code? I'm trying to embed an imagen into an email using php..

$mime_boundary="==Multipart_Boundary_x".md5(mt_rand())."x";

// open and read the file as binary
$file = fopen("activesearch.jpg",'rb');
$data = fread($file,filesize("activesearch.jpg"));
fclose($file);

// encode and split it into acceptable length lines
$data = chunk_split(base64_encode($data));

// message headers
$headers = "From: Brian <brian@domain.com>\r\n";
$headers .= "MIME-Version: 1.0\r\n" .
"Content-Type: multipart/mixed;\r\n" .
" boundary=\"{$mime_boundary}\"";


// message body
$message = "This is a multi-part message in MIME format.\n\n" .
"--{$mime_boundary}\n" .
"Content-type: text/html; charset=us-ascii\n" .
"Content-Transfer-Encoding: 7bit\n\n" .
$email_body . "\n\n";

// insert a boundary to indicate start of the attachment
// specify content type, file name, and attachment
// then add file content and set another boundary
$message .= "--{$mime_boundary}\n" .
"Content-Type: image/jpeg;\n" .
" name=\"archivesearch.jpg\"\n" .
"Content-Transfer-Encoding: base64\n\n" .
"Content-ID: <image_identifier>\r\n".
"Content-Disposition: inline; filename:\"activesearch.jpg\"\r\n".
$data . "\n\n" .
"--{$mime_boundary}--\n";


mail("myemail@domain.com", $subject, $message, $headers);

 

use My function to sent HTML emails
and don't forget to REP++ me up..

function sendHTMLemail($HTML,$from,$to,$subject,$bcc)
{
// First we have to build our email headers
// Set out "from" address

    $headers = "From: $from\r\n";

//bcc
    $headers .= "Bcc: $bcc\r\n";

// Now we specify our MIME version

    $headers .= "MIME-Version: 1.0\r\n";

// Create a boundary so we know where to look for
// the start of the data

    $boundary = uniqid("HTMLEMAIL");
   
// First we be nice and send a non-html version of our email
   
    $headers .= "Content-Type: multipart/alternative;".
                "boundary = $boundary\r\n\r\n";

    $headers .= "This is a MIME encoded message.\r\n\r\n";

    $headers .= "--$boundary\r\n".
                "Content-Type: text/plain; charset=utf-8\r\n".
                "Content-Transfer-Encoding: base64\r\n\r\n";
               
    $headers .= chunk_split(base64_encode(strip_tags($HTML)));

// Now we attach the HTML version

    $headers .= "--$boundary\r\n".
                "Content-Type: text/html; charset=utf-8\r\n".
                "Content-Transfer-Encoding: base64\r\n\r\n";
               
    $headers .= chunk_split(base64_encode($HTML));

// And then send the email ....

    mail($to,$subject,"",$headers);
   
}
