require_once, function

I'm a noob, I know very little about php. Anyway, my page won't load at all, browser says its redirecting in a way that is not loading. As the title suggests I think the issue is with one of the php files I include with require_once(). Let me just show you:

thumbnail.php:

<?php
if(!function_exists("makethumbnail"))
{
    //die("right before function definition");
    function makethumbnail($src,$new_name,$new_width,$new_height)
    {
        die("inside makethumbnail");
        $si = imagecreatefromjpeg($src);
        $w = imagesx($si);
        $h = imagesy($si);
        $vi = imagecreatetruecolor($new_width,$new_height);
        imagecopyresampled($vi,$si,0,0,0,0,$new_width,$new_height,$w,$h);
        imagejpeg($vi,$new_name);
    }
}
?>

index.php:

<?php 
require_once("shopsite/thumbnail.php");
require_once("shopsite/checksession.php");
die("made it past the require_once");
$con = mysql_connect('localhost','jddancks','csc255');
mysql_select_db('test',$con);
$q = mysql_query("select prod_name,image_name,type1,type2 from Product",$con) or die("its the mysql");
$row = mysql_fetch_assoc($q);
$totalRows_Recordset1 = mysql_num_rows($q);
?>

            $cnt=$cnt+1;
            if($cnt>12) die("cnt larger than 12");
       }
       while($row = mysql_fetch_assoc($q));
       ?>
       </ul>

<?php mysql_free_result($row);
mysql_close($con); ?>

I want to insert images into a jquery carousel so a visitor can browse items they may want to purchase. I've never used jcarousel so I don't know if what I have works, I'm pretty sure thats not the problem. I guess its just one f those things you need a second pair of eyes for. The die statements in thumbnail.php make me believe that is the culprit, but it won't make it to the first line of the function, which is really confusing. I don't know how the php preporcessor works, other than its client-side.
