PHP- createThumbnail() function error

[caveman]

Hi i am using PHP to upload picture files to a file in my server, but for some reason it will not create thumbnails of the upload, all that happens is that where the thumbnail is meant to be displayed is a square with an x in it. No error message is displayed, can anyone help me? I cant see where the error is... im trying to save the thumbnail to file 'thumbnail/'

PHP code:
<?php
function uploadImage($in putName, $uploadDir)
{
$image = $_FILES[$inputName];
$imagePath = '';
$thumbnailPath = '';

if (trim($image['tmp_name']) != '') {
$ext = substr(strrchr( $image['name'], "."), 1);

$imagePath = md5(rand() * time()) . ".$ext";
$result = move_uploaded_f ile($image['tmp_name'], $uploadDir . $imagePath);

if ($result) {

$thumbnailPath = md5(rand() * time()) . ".$ext";
$result = createThumbnail ($uploadDir . $imagePath, $uploadDir . 'thumbnail/' . $thumbnailPath, THUMBNAIL_WIDTH );

if (!$result) {
unlink($uploadD ir . $imagePath);
$imagePath = $thumbnailPath = '';
} else {
$thumbnailPath = $result;
}
} else {

$imagePath = $thumbnailPath = '';
}

}


return array('image' => $imagePath, 'thumbnail' => $thumbnailPath) ;
}

function createThumbnail ($srcFile, $destFile, $width, $quality = 75)
{
$thumbnail = '';

if (file_exists($s rcFile) && isset($destFile ))
{
$size = getimagesize($s rcFile);
$w = number_format($ width, 0, ',', '');
$h = number_format(( $size[1] / $size[0]) * $width, 0, ',', '');

$thumbnail = copyImage($srcF ile, $destFile, $w, $h, $quality);
}

// return the thumbnail file name on sucess or blank on fail
return basename($thumb nail);
}


function copyImage($srcF ile, $destFile, $w, $h, $quality = 75)
{
$tmpSrc = pathinfo(strtol ower($srcFile)) ;
$tmpDest = pathinfo(strtol ower($destFile) );
$size = getimagesize($s rcFile);

if ($tmpDest['extension'] == "gif" || $tmpDest['extension'] == "jpg")
{
$destFile = substr_replace( $destFile, 'jpg', -3);
$dest = imagecreatetrue color($w, $h);
//imageantialias( $dest, TRUE);
} elseif ($tmpDest['extension'] == "png") {
$dest = imagecreatetrue color($w, $h);
//imageantialias( $dest, TRUE);
} else {
return false;
}

switch($size[2])
{
case 1: //GIF
$src = imagecreatefrom gif($srcFile);
break;
case 2: //JPEG
