How can we add in code a product to the cart with a custom option type file in Magento?

It works in Magento 1.7 but I haven't tested it on another versions

// the path of the file, relative to Magento base directory.
// For example /media/image.jpg
$image = "YOURFILE.JPG";
// the ID of the product
$product_id  = XXX;

$product     = Mage::getModel('catalog/product')->load($product_id);

$cart = Mage::getModel('checkout/cart');
$cart->init();
$params = array(
    'product' => $product_id,
    'qty' => 1,
    'options' => array(
        12345 => array(
                'quote_path' => $image,
                'secret_key' => substr(md5(file_get_contents(Mage::getBaseDir() . $image)), 0, 20)),
    )
);

$cart->addProduct($product, $params);
$cart->save();

Mage::getSingleton('checkout/session')->setCartWasUpdated(true);
