[SuperSavio]

ecco il codic che ho sviluppato in 2 minuti dovrebbe funzionare nn ho testato

<?php

       header("Location: upload.php"); /* Redirect browser */
       /* qui invece dell header e dell'exit metti il codice sql che inserisce nel db tutte le info e percorso all'img di default di cui te parlavi */
          
       exit(); //exit the script and don't do anything else.
