sì hai ragione... ero partito da lì ma poi ho cominciato a fare tentativi sbagliati.

La pagina del form ha questa struttura:

<form action="modifica.php" method="post" enctype="multipart/form-data" name="form1">

  

<?php 
  include ("config.inc.php"); 
  include ("connect.php");
  

  $id = $_GET['id'];
    
  $query ="SELECT * FROM $tabarticoli WHERE idart='$id'";
  $result = mysql_query($query,$db);
   while($row = mysql_fetch_array($result)) { 
  
  echo "[b]ID:[/b] $id";
  $img1 = $row['immagine']; 
  $img2 = $row['immagine2'];
  $img3 = $row['immagine3'];
  $percorso = "TBASE/img/";
  
//$_FILES['userfile']['name']
  ?>
    <input name="posted" type="hidden" id="posted" value="posted" />
    <input name="id" type="hidden" value="<?php echo $row['idart']; ?>" />
  </p>
