pChart does not render to web browser, only shows missing image

pCharts documentation says that you should be able to render the image to the browser using this code.

mypic.php

$myPicture->stroke;

mypage.html

<IMG SRC=‘mypic.php‘>

The img tag is supposed to invoke the php script. Within the PHP script, the stroke function sets the content-type: image/png.

So here is what I have:

netsales.php

<?php
     include('../class/pData.class.php');
     include('../class/pDraw.class.php');
     include('../class/pImage.class.php');

     /* query sales and create new image */

     $myPicture->stroke;
?>

index.php

<?php
     include ('netsales.php');
?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
</head>
<body>
     <div>
          <img src="netsales.php" />
     </div>
</body>
</html>

I'm not getting any errors, just the red X for a missing image.

try removing the

<?php
     include ('netsales.php');
?>

From index.php, and add

header('Content-Type: image/png');

Before the Stroke call.
