Hjælp til output, som skal væl

Hey Eksperter - I need help!!!!!!!!!!!!!!!
Når man klikker på submit, bliver teksten "filen er uploaded" vist ovenover selve formularen. Kan man lave scriptet sådan, at man bliver smidt til en ny side, efter at man har klikket på submit.

<?php
function resize( $filename, $newfilename, $maxw, $maxh )
{
    $srcim = imagecreatefromjpeg( $filename );
    $ow = imagesx( $srcim );
    $oh = imagesy( $srcim );
    $wscale = $maxw / $ow;
    $hscale = $maxh / $oh;
    $scale = ( $hscale < $wscale ? $hscale : $wscale );
    $nw = round( $ow * $scale, 0 );
    $nh = round( $oh * $scale, 0 );
    $dstim = imagecreatetruecolor( $nw, $nh );
    imagecopyresampled( $dstim, $srcim, 0, 0, 0, 0, $nw, $nh, $ow, $oh );
    imagejpeg( $dstim, $newfilename, 85 );
    imagedestroy( $dstim );
    imagedestroy( $srcim );
    return file_exists($newfilename);
}
require('connect.php');

$allowedFiles = array('jpg');
$curDir      = getcwd();
$uploadDir    = '/upload/';
$output      = '<div id="centerDiv">';

if(isset($_POST['upload']) && $_FILES['myFile']['size'] > 0)
{
    $ext = strtolower(end(explode('.',$_FILES['myFile']['name'])));
    if(in_array($ext,$allowedFiles))
    {
        $design  = mysql_real_escape_string(strip_tags($_POST['mydesign']));
        $email  = mysql_real_escape_string(strip_tags($_POST['myemail']));
        $kategori  = mysql_real_escape_string(strip_tags($_POST['mykategori']));
        $header  = mysql_real_escape_string(strip_tags($_POST['myHeader']));
        $pris  = mysql_real_escape_string(strip_tags($_POST['mypris']));
        $comment = mysql_real_escape_string(strip_tags($_POST['myText']));
        $file = md5(uniqid(rand(), true)) . '.jpg';

        if(resize($_FILES['myFile']['tmp_name'], $curDir . $uploadDir . $file, 150, 150))
