Ho creato questo script che permette di fare il ridimensionamento e l'upload di foto, attualmente funziona alla perfezione però ora vorrei salvare 2 copie dell'immagine, una sarà l'immagine originale, quindi il nome restera invariato, mentre all'immagine ridimensionata vorrei accodare una stringa del tipo "NOMEFOTO-small.jpg" però non riesco a capire come fare, mi potete aiutare.

Questo è il codice:
Codice PHP:
<?php ini_set("memory_limit", "200000000"); // for large images so that we do not get "Allowed memory exhausted"?>
<?php
// upload the file
if ((isset($_POST["submitted_form"])) && ($_POST["submitted_form"] == "image_upload_form")) {
 // file needs to be jpg,gif,bmp,x-png and 4 MB max
 if (($_FILES["image_upload_box"]["type"] == "image/jpeg" || $_FILES["image_upload_box"]["type"] == "image/pjpeg" || $_FILES["image_upload_box"]["type"] == "image/gif" || $_FILES["image_upload_box"]["type"] == "image/x-png") && ($_FILES["image_upload_box"]["size"] < 4000000))
 {
  // if uploaded image was JPG/JPEG
  if($_FILES["image_upload_box"]["type"] == "image/jpeg" || $_FILES["image_upload_box"]["type"] == "image/pjpeg"){
   $image_source = imagecreatefromjpeg($_FILES["image_upload_box"]["tmp_name"]);
  }
  // if uploaded image was GIF
  if($_FILES["image_upload_box"]["type"] == "image/gif"){
   $image_source = imagecreatefromgif($_FILES["image_upload_box"]["tmp_name"]);
  }
  // BMP doesn't seem to be supported so remove it form above image type test (reject bmps)
  // if uploaded image was BMP
  if($_FILES["image_upload_box"]["type"] == "image/bmp"){
   $image_source = imagecreatefromwbmp($_FILES["image_upload_box"]["tmp_name"]);
  }
  // if uploaded image was PNG
  if($_FILES["image_upload_box"]["type"] == "image/x-png"){
   $image_source = imagecreatefrompng($_FILES["image_upload_box"]["tmp_name"]);
  }
  $remote_file = "foto/".$_FILES["image_upload_box"]["name"];
  imagejpeg($image_source,$remote_file,80);
  chmod($remote_file,0644);
  $new_w = 120;
  $new_h = 120;

  // PAESAGGIO
  if ($orig_w > $orig_h ) {
   $crop_w = round($orig_w * $h_ratio);
   $crop_h = $new_h;
   $x = ($orig_w - $orig_h) / 2;
 
  // RITRATTO
  } elseif ($orig_w < $orig_h ) {
   $crop_h = round($orig_h * $w_ratio);
   $crop_w = $new_w;
   $y = ($orig_h - $orig_w) /2;
  // QUADRATO
  } else {
   $crop_w = $new_w;
   $crop_h = $new_h;
  }
  $new_image = imagecreatetruecolor($new_w,$new_h);

  imagejpeg($new_image,$remote_file,80);
  imagedestroy($new_image);
  imagedestroy($image_source);
 
  header("Location: submit.php?upload_message=image uploaded&upload_message_type=success&show_image=".$_FILES["image_upload_box"]["name"]);
  exit;
 }
 else{
  header("Location: submit.php?upload_message=make sure the file is jpg, gif or png and that is smaller than 4MB&upload_message_type=error");
  exit;
