Comment télécharger un fichier vignette dans un seau amazon s3?

Question

Salut, je suis nouveau à Amazon et j'ai très peu d'idée de travailler avec des fichiers.J'essaie de télécharger une image miniature dans le seau. Je pourrais télécharger une image dans localhost mais je ne pouvais pas le télécharger en bucket.I pourrait télécharger l'image originale dans le seau, voici mon 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;

Essayez ce bon chemin d'accès où télécharger la vignette dans la racine de votre serveur.

$upload_img = Upload('image','uploads/','',TRUE,'uploads/thumbs/','200','160'); 
    $upload_img1 = Upload('image','products/','',TRUE,'products/','200','160');

    //$fileTempName12 = $_FILES[$upload_img1]['tmp_name']; comment this line

    //full path of the thumbnail image 
    $thumb_src = 'products/'.$upload_img1;
