How to save thumbnails?

I'm having trouble saving the files.

The goal is to save the converted images after they are uploaded, which I think have managed, with the following code.

---------------- Code for my resizing ------------------

<script type="text/javascript" src="iuembed.js"></script>

<script type="text/javascript">

var iu = new ImageUploaderWriter("ImageUploader", 623, 500);

//Configure License Keys

iu.addParam("LicenseKey", "71050-10000-FDFCC-DC8BA-E1DF6;72050-10000-54141-4BAFB-F039C");

//Max antal filer samt fil størrelser.

iu.addParam("MaxFileCount", "2");

iu.addParam("MaxFileSize", "3145728");

iu.addParam("MaxTotalFileSize", "10485760");

//Layout

iu.addParam("PaneLayout", "TwoPanes");

iu.addParam("AllowRotate", "true");

iu.addParam("UploadSourceFile", "false");

iu.addParam("UploadThumbnail1FitMode", "ActualSize");

//Configure colors.

iu.addParam("BackgroundColor", "#ffffff");

iu.addParam("SplitterLineColor", "#0066cc");

//Configure thumbnail settings.

iu.addParam("UploadThumbnail1FitMode", "Fit");

iu.addParam("UploadThumbnail1Width", "550");

iu.addParam("UploadThumbnail1Height", "413");

iu.addParam("UploadThumbnail1JpegQuality", "70");

//Configure URL where to redirect after upload.

iu.addParam("RedirectUrl", "index.php");

//Configure URL files are uploaded to.

iu.addParam("Action", "upload.php");

iu.writeHtml();

</script>

---------------- Code for my upload ------------------

<?php

//This variable specifies relative path to the folder, where the gallery

//with uploaded files is located.

$galleryPath = "gallery/";

$absGalleryPath = realpath($galleryPath) . "/";

//Get total number of uploaded files (all files are uploaded in a single package).

$fileCount = $_POST ["FileCount"];

//Iterate through uploaded data and save the original file and thumbnail.

for ($i = 1; $i <= $fileCount; $i++)

{

//Get first thumbnail (the single thumbnail in this code sample) and save it to disk.

$thumbnail1Field = "Thumbnail1_" . $i;

move_uploaded_file($_FILES[$thumbnail1Field]["tmp_name"],

$absGalleryPath . "gallery/" . $fileName . ".jpg");

}

?>

---------------- Code for my upload ------------------

So what do i need to change or insert?
