如何将缩略图文件上传到亚马逊s3存储桶?

Hi I am new to amazon and have very little idea working with files.I am trying to upload a thumbnail image into bucket. I could upload a image in localhost but I could not upload it in bucket.I could upload the original image to the bucket, Here is my code

<?php
//include the S3 class
            if (!class_exists('S3'))require_once('S3.php');

            //AWS access info
            if (!defined('awsAccessKey')) define('awsAccessKey', '');
            if (!defined('awsSecretKey')) define('awsSecretKey', '');

            //instantiate the class
            $s3 = new S3(awsAccessKey, awsSecretKey);


function Upload($field_name = '', $target_folder = '', $file_name = '', $thumb = FALSE, $thumb_folder = '', $thumb_width = '', $thumb_height = ''){
    //folder path setup
    $target_path = $target_folder;
    $thumb_path = $thumb_folder;

    //file name setup
    $filename_err = explode(".",$_FILES[$field_name]['name']);
    $filename_err_count = count($filename_err);
    $file_ext = $filename_err[$filename_err_count-1];
    if($file_name != '')
    {
        $fileName = $file_name.'.'.$file_ext;
    }
    else
    {
        $fileName = $_FILES[$field_name]['name'];
    }

    //upload image path
    $upload_image = $target_path.basename($fileName);

    //upload image
    if(move_uploaded_file($_FILES[$field_name]['tmp_name'],$upload_image))
    {
        //thumbnail creation
        if($thumb == TRUE)
        {
            $thumbnail = $thumb_path.$fileName;
            list($width,$height) = getimagesize($upload_image);
            $thumb_create = imagecreatetruecolor($thumb_width,$thumb_height);
            switch($file_ext){
                case 'jpg':
                    $source = imagecreatefromjpeg($upload_image);
                    break;
                case 'jpeg':
                    $source = imagecreatefromjpeg($upload_image);
                    break;
                case 'png':
                    $source = imagecreatefrompng($upload_image);
                    break;

                    $source = imagecreatefromgif($upload_image);
                    break;
                default:
                    $source = imagecreatefromjpeg($upload_image);
            }
            imagecopyresized($thumb_create,$source,0,0,0,0,$thumb_width,$thumb_height,$width,$height);
            switch($file_ext){
                case 'jpg' || 'jpeg':
