Ciao a tutti, ho uno script che carica un'immagine e la ridimensiona, vorrei sapere come posso fare per applicare ad essa un watermark.

Posto il codice che si occupa dell'upload dell'immagine:
Codice PHP:
if($uploadedfile <> "none") {


$finale = $_POST["nome_foto"];
$uploadedfile_name = $finale . ".jpg";
$percorso = $_FILES['uploadedfile']['tmp_name'];
if(!move_uploaded_file($percorso, "foto/" . $uploadedfile_name))
}

$fullsize           = @imagecreatefromjpeg("foto/" . $uploadedfile_name);
$fullsize_height = @imagesy($fullsize);
$fullsize_width  = @imagesx($fullsize);
         
list($larg, $alt)  = @getimagesize("foto/" . $uploadedfile_name);
if($larg > 700) $thumb_width = 700; 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, "foto/" . $uploadedfile_name);
@imagedestroy($thumb);
if($flag == 0) $path = "foto/" . $uploadedfile_name; else $path = "";
