upload, ridimensionamento e...mi manca il salvataggio

[cane-nero]

Ciao, sono riusito a far funzionare questo script il cui scopo è quello di ricevere in input un'immagine da un form, ridimensionarla e visualizzarla. Quello che non riesco a capire è come fare per salvare l'immagine ridimensionata!!

Ecco lo script:

<?php

// Check if file was uploaded ok
if( ! is_uploaded_file($_FILES['image']['tmp_name']) || $_FILES['image']['error'] !== UPLOAD_ERR_OK)
{
    exit('File not uploaded. Possibly too large.');
}

// Create image from file
switch(strtolower($_FILES['image']['type']))
{
    case 'image/jpeg':
        $image = imagecreatefromjpeg($_FILES['image']['tmp_name']);
        break;
    case 'image/png':
        $image = imagecreatefrompng($_FILES['image']['tmp_name']);
        break;
    case 'image/gif':
        $image = imagecreatefromgif($_FILES['image']['tmp_name']);
        break;
    default:
        exit('Unsupported type: '.$_FILES['image']['type']);
}

// Target dimensions
$max_width = 240;
$max_height = 180;

// Get current dimensions
$old_width  = imagesx($image);
$old_height = imagesy($image);

// Calculate the scaling we need to do to fit the image inside our frame
$scale      = min($max_width/$old_width, $max_height/$old_height);

// Get the new dimensions
$new_width  = ceil($scale*$old_width);
$new_height = ceil($scale*$old_height);

// Create new empty image
$new = imagecreatetruecolor($new_width, $new_height);

// Resize old image into new

		
imagecopyresampled($new, $image,0, 0, 0, 0,$new_width, $new_height, $old_width, $old_height);

		// Catch the imagedata
ob_start();
imagejpeg($new, NULL, 90);
$data = ob_get_clean();

// Destroy resources
imagedestroy($image);
imagedestroy($new);

// Set new content-type and status code
header("Content-type: image/jpeg", true, 200);

// Output data
echo $data;
?>

Salvare come file?
