Simpel maade af vedhaefte billeder til HTML mail?

Hej eksperter,

jeg sidder og mangler en simpel men virksom maade at vedhaefte billeder til mine HTML mails.

function mailme($fromname, $fromaddress, $toname, $toaddress, $subject, $message)
{
  $headers  = "MIME-Version: 1.0\n";
  $headers .= "Content-type: text/html; charset=iso-8859-1\n";
  $headers .= "X-Priority: 3\n";
  $headers .= "X-MSMail-Priority: Normal\n";
  $headers .= "X-Mailer: php\n";
  $headers .= "From: \"".$fromname."\" <".$fromaddress.">\n";
  return mail($toaddress, $subject, $message, $headers);
}
