Código PHP:

  $uploaddir = "/"; 
                    $uploadfile = $uploaddir . ($_FILES["imagen"]["name"]); 
                    $id = $_SESSION['foto']; 
                    $name = $_SESSION['foto'].".jpg"; 
                    $tipo = explode("/", $_FILES["imagen"]["type"]); 
                     
                     
                     
                    if($_FILES["imagen"]["size"] < 200000 && ($tipo[0] == "image")) 
                            { 
                                if (is_uploaded_file($_FILES['imagen']['tmp_name'])) 
                                        { 
                                         
                                        $dir = opendir("./catalogue/"); 
                                         
                                        while($borrar = readdir($dir)){ 
                                         
                                        if ($borrar == $name){ 
                                        unlink("./catalogue/".$name); 
                                        } 
                                         
                                        } 
                                        closedir($dir); 
                                         
                                            move_uploaded_file($_FILES['imagen']['tmp_name'], "./catalogue/".$name); 
                                            //unset($_SESSION['foto']); 
                                            header ("location:modificar.php?acn=modif&id=$id"); 
                                             
                                            //$datos = getimagesize("./catalogue/".$name); 
                                             
                                            //echo $datos[0]. "  " . $datos[1]  . " | " .$datos[2] . "<br>" . $_FILES['imagen']['type'];    
                                             
                                        } 
                                else  
                                        { 
                                            echo "El archivo: ". ($_FILES["imagen"]["name"]) .",  no se cargo correctamente"; 
                                            exit; 
                                        } 
                                                 
                            } 
                    else 
                            { 
                                echo "El archivo: ". ($_FILES["imagen"]["name"]) . " ,  tiene un formato no valido o su tamaño es mayor a 200 kb" ; 
                                exit;
