php send 2 inline images in email

I am sending an email in html format. This is working fine, and I have simplified it for this example. I need to take this simple code and add functionality to send (2) inline image files (variable for filename is $clientlogo and $footerlogo). The image in the email when the email is opened. The file will already exist on the server. I know that some email programs block images, but it is necessary to send the image. // heres the code without inline image stuff $clientlogo = "/img/[login to view URL]"; $footerlogo = "/img/[login to view URL]"; $userfullname="test userfullname"; $prtitle="test pr title"; $prby="Dale Shad"; $useremail = "Daleshad@[login to view URL]"; $emailBody = "<center><img src=".$clientlogo."></center><br/>" "<div style=font-family:Arial;font-size:11pt;>"; $emailBody .="Contact: ".$userfullname."<br/>"; $emailBody .="Email: ".$useremail."<br/><br/><br/>"; $emailBody .= "<center><div style=font-size:16pt;font-weight:bold;>".$prtitle."</div>"; $emailBody .= "<b>".$prby."</b></center>"; $fromemail ="Daleshad@[login to view URL]"; $to = "daleshad@[login to view URL]"; $subject = $emailSubject; $body = $emailBody; $headers = "From: <".$fromemail.">\r\n"; $headers .= "MIME-Version: 1.0" . "\r\n"; $headers .= "Content-type:text/html;charset=iso-8859-1" . "\r\n"; if (mail($to, $subject, $body, $headers)) {echo("Done");} else {echo("failed...");}
