It was a good suggestion. Even better was that it worked!
Here is some example code:
$dbuf .= "<table width=\"650\" border=\"0\" cellpadding=\"2\" cellspacing=\"2\" bordercolor=\"#BAE860\">";
$dbuf .= "<tr>";
$dbuf .= "<td width=\"374\"><div align=\"left\"><img src=\"http://www.centricav.com/new/centriclogo.gif\" width=\"175\" height=\"70\"></div></td>";
$dbuf .= "<td width=\"374\"><div align=\"right\"><img src=\"http://www.centricav.com/new/iquotelogo.gif\" width=\"175\" height=\"73\"></div></td>";
$dbuf .= "</tr>";
$dbuf .= "</table>";
$myname = "CentricAV";
$myemail = "orders@centricav.com";
$subject = "CentricAV iQuote Order Received - iQuote # " . $quoteID;
$from = $Contact . " <" . $UserEmail . ">";
$to = $OrderEmail . ", " . $myname . " <" . $myemail . ">";
$to .= ", " . $from;
mail($to,$subject,$dbuf,"From: " . $from . "\nContent-Type: text/html; charset=iso-8859-1")
Good luck!
