Image Processing - Upload/Resize/Create Thumb & Save

Question

I'm looking for some help. I have the following code which uploads the image & creates a thumbnail and stores them in the appropriate folders... But my problem is space.. the uploaded main images are HUGE 4320 x 3240 and the site takes ages to load... I only want 2 images: A main image max width 1024, and a thumbnail max width 100....

UPDATE: Now works and resizes main image and creates thumbnail but only works on small image sizes < 2500px wide... but I need it to work on an image 4320px wide....

here's my code so far:

    <?php ob_start();
session_start(); 
include("../../config.php");
ini_set("memory_limit", "500M");
$folder = "../images/stock/".$_SESSION['info_id']."";
$thumbs =$folder.'/thumbs/';
if(!file_exists($folder)){
    mkdir ($folder,0777);
    $uploadfolder = $folder."/";
    //echo $folder.'<br>';
    }
    else
    {
        //echo 'folder already created<br>';
        $uploadfolder = $folder."/";
        //echo $folder.'<br>';
    }

if(!file_exists($thumbs)){
    mkdir($thumbs,0777);
    $thumbnailfolder = $thumbs ;
    //echo $thumbs.'<br>';
}else{
    $thumbnailfolder = $thumbs ;
    //echo $thumbnailfolder.'<br>';

}

$allowedfiletypes = array("jpeg","jpg");
//$uploadfolder = $s;
$thumbnailheight = 100; //in pixels
$imagesresizeheight = 500;

$action = $_POST['action'];
if ($action == "upload") {
    //$_SESSION['result'] = "Uploading image... " ;

    if(empty($_FILES['uploadimage']['name'])){
        $_SESSION['result'] = "<strong>Error: File not uploaded 1!</strong><br>" ;
    } else {
            $uploadfilename = $_FILES['uploadimage']['name'];
        $fileext = strtolower(substr($uploadfilename,strrpos($uploadfilename,".")+1));
        if (!in_array($fileext,$allowedfiletypes)) { $_SESSION['result'] = "<strong>Error: Invalid file extension!</strong><br>" ; }
        else {

            $fulluploadfilename = $uploadfolder.$uploadfilename ;
            if (move_uploaded_file($_FILES['uploadimage']['tmp_name'], $fulluploadfilename)) {
                $im = imagecreatefromjpeg($fulluploadfilename);
                if (!$im) { $_SESSION['result'] = "<p><strong>Error: Couldn't Resize Image!</strong><br>" ; }
