Passing PHP variables from one page to another

Hello-
I'm having trouble figuring out how to transport a variable from one php file to another. Specifically, the name of an image, to be used as a subject in a form mail. I don't even really have the proper vocabulary to describe this, so I'll just try to show my code.
Here's the test website in question:
http://www.grymttr.com/raj/RajTest/portfolio/
When you go to the "portfolio" page, and click on the album (only one at the moment). If you see a picture you are interested in, you click on it, which triggers the file "popup2.php"
Quote<?php error_reporting(0); if (isset($_GET['dl'])) {
$file = str_replace('/', DIRECTORY_SEPARATOR, $_GET['src']);
if (strpos($file, '..') !== false) {
exit;
}
$name = basename($file);
$info = pathinfo($name);
$ext = $info['extension'];
$full_path = dirname(__FILE__) . $file;
header("Content-Disposition: attachment; filename=$name");
switch(strtolower($ext)) {
case 'jpg':
$ct = 'image/jpeg';
break;
case 'gif':
$ct = 'image/gif';
break;
case 'png':
$ct = 'image/png';
break;
default:
$ct = 'application/octet-stream';
break;
}
header('Content-type: ' . $ct);
header('Content-length: ' . filesize($full_path));
$disabled_functions = explode(',', ini_get('disable_functions'));
if (is_callable('readfile') && !in_array('readfile', $disabled_functions)) {
readfile($full_path);
} else {
die(file_get_contents($full_path));
}
} else { ?><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"

if (isIE()) {
var h = document.documentElement.clientHeight;
} else {
var h = window.innerHeight;
}
var w = document.body.clientWidth;
var adj_w = img_w - w;
var adj_h = img_h - h;
window.resizeBy(adj_w, adj_h);
window.focus();
}
</script>
<link href="mail.css" rel="stylesheet" type="text/css" />
</head>
<body>
<?php
if (strpos($_GET['src'], 'p.php?a=') !== false) {
$src = $_GET['src'];
$bits = explode('?a=', $src);
$src = $bits[0] . '?a=' . urlencode($bits[1]);
} else {
$src = strip_tags($_GET['src']);
}
?><div id="container">
<img class="image" src="<?php echo($src); ?>" alt="<?php echo(strip_tags($_GET['title'])); ?>" />
<div id="form">
<form method="POST" action="mailer.php">
Subject: "<?php echo(strip_tags($_GET['title'])); ?>"
Name:
<input type="text" name="name" size="29">
E-Mail:
<input type="text" name="email" size="29">
<input type="checkbox" name="check[]" value="print"> print
<input type="checkbox" name="check[]" value="matte"> matte
<input type="checkbox" name="check[]" value="frame"> frame
Message:
<textarea rows="7" name="message" cols="33"></textarea>
<input type="submit" value="Submit" name="submit">
</form>
</div></div>
</body>
</html><?php } ?>
and then I have "mailer.php" which actually sends the mail with the variables entered in the form above. The lines highlighted in green grab the "title" of the image, like "GLS002.jpg", which is what I want to be the subject of the e-mail.
Quote
<?php
if(isset($_POST['submit'])) {
$to = "greg@grymttr.com";
$subject = $_GET['title'];
$name_field = $_POST['name'];
$email_field = $_POST['email'];
$message = $_POST['message'];
foreach($_POST['check'] as $value) {
$check_msg .= "Checked: $valuenn";
}
$body = "From: $name_fieldnn E-Mail: $email_fieldnn Subject: $subjectnn Message:nn $messagenn $check_msg";
echo "Data has been submitted to $to!";
mail($to, $subject, $body);
} else {
echo "blarg!";
}
?>
I know the line in red is wrong, but I don't know how to get the title of the image from "popup2.php". If you go to the site and click on an image during the slideshow, you will see the pop-up open, with the title of the window and the "Subject: ....." line filled out correctly, but I can't figure out how to get that variable into the mailer.php file as the subject of the e-mail that gets sent. It's sort of critical, as that's the identification of the image in question. Help!
