Perchè non carica la foto?

[mariolone]

Ciao a tutti, sto usando un piccolo pezzo di codice che carica un'immagine e a sua volta la ridimensiona, lo script è il seguente ma non riesco a capire perchè non funziona.

form.html

<form name="info" method="post" action="send.php" enctype="multipart/form-data">
<input name="uploadedfile" type="file" id="uploadedfile" class="input_class" />
<input type="hidden" name="max_file_size" value="300000" />
<input type="submit" name="submit" values="Carica" />
</form>

send.php

if($uploadedfile <> "none") {
 $new_name = 10;
 $uploadedfile_name = $new_name . ".jpg";
 if(!copy($uploadedfile,"photo/$uploadedfile_name")) {
  $flag = 1;
 } else {
    $flag = 0;
  }
}
//Inizio il resize 
$fullsize        = @imagecreatefromjpeg("photo/$uploadedfile_name");
$fullsize_height = @imagesy($fullsize);
$fullsize_width  = @imagesx($fullsize);
 
list($larg, $alt) = @getimagesize("photo/$uploadedfile_name");
if($larg > 450) {
$thumb_width = 450;
} else {
    $thumb_width = $larg;
    }
 
$thumb_height = @floor($fullsize_height/($fullsize_width/$thumb_width));
 
$thumb=@imagecreatetruecolor($thumb_width,$thumb_height);
@imagecopyresampled($thumb,$fullsize,0,0,0,0,$thumb_width,$thumb_height,$fullsize_width,$fullsize_height);
 
@imagedestroy($fullsize);
@imagejpeg ($thumb,"photo/$uploadedfile_name");
@imagedestroy($thumb);

if($flag == 0)
 $path = "photo/" . $uploadedfile_name;
  else 
   $path = "";

echo $path;
