Unhappy Chapter 7 Image not displaying

I'm trying to get the "check_image.php" code to work. Everything seems to be there but the image does not display, only a place holder.
Here is the code I'm using:
Code:
<?php

//connect to the database
$link = mysql_connect("localhost", "john", "**********")
  or die("Could not connect: " . mysql_error());
mysql_select_db("MovieSite", $link) 
  or die (mysql_error());
?>
<pre>
<?php
  echo "<br>_POST<br>"  ;
  print_r($_POST);
  echo "<br>_FILES<br>";
  print_r($_FILES);
  echo "<br>";
?>
</pre>
<?php

//make variables available
$image_caption = $_POST['image_caption'];
$image_username = $_POST['image_username'];
$image_tempname = $_FILES['image_filename']['name'];
$today = date("Y-m-j");

echo "<br>image_tempname: " . $image_tempname;
echo "<br>";

//upload image and check for image type
$ImageDir ="/var/www/images/";
$ImageName = $ImageDir . $image_tempname;

echo "<br>ImageName: " . $ImageName;
echo "<br>";

if (move_uploaded_file($_FILES['image_filename']['tmp_name'], 
                      $ImageName)) {

			echo "<br>File Moved";
  //get info about the image being uploaded
  list($width, $height, $type, $attr) = getimagesize($ImageName);

  switch ($type) {
    case 1:
      $ext = ".gif";
      break;
    case 2:
      $ext = ".jpg";
      break;
    case 3:
      $ext = ".png";
      break;
    default:
      echo "Sorry, but the file you uploaded was not a GIF, JPG, or " .
           "PNG file.<br>";
      echo "Please hit your browser's 'back' button and try again.";
  }

 //insert info into image table

  $insert = "INSERT INTO images
            (image_caption, image_username, image_date)
            VALUES
            ('$image_caption', '$image_username', '$today')";
  $insertresults = mysql_query($insert)
    or die(mysql_error());

  $lastpicid = mysql_insert_id();

    $newfilename =  $ImageDir . $lastpicid . $ext;
    
    echo "<br>newfilename: ". $newfilename;
    echo "<br>ImageName: ". $ImageName;
    echo "<br>";

   rename($ImageName, $newfilename);
 
}

?>
<html>
<head>
<title>Here is your pic!</title>
</head>
<br><br>
<p>Here is the picture you just uploaded to our servers:</p>
<img src="images/<?php echo $lastpicid . $ext; ?>" align="left">
<strong><?php echo $image_caption; ?></strong><br>
This image  is a <?php echo $ext; ?> image.<br>
It is <?php echo $width; ?> pixels wide
and <?php echo $height; ?> pixels high.<br>
It was uploaded on <?php echo $today; ?>.
</body>
</html>
Again everything seems to be on the web page but the picture. I'd attach a screen shot but since I'm new I guess I can't.

Any ideas what I'm doing wrong or is there some setting that needs tweaking?

Thanks,
John
