Wordpress - adding Featured image to custom Post Type

Question

I'm trying to add a Featured Image to my theme but not for Posts or Pages - I've created a custom type called Properties (its for an estate agent), so how do I enable Featured Image, as it doesn't appear in the sceen options?

Hope someone can help,

$property  = new Cuztom_Post_Type( 'Property', array(
    'supports' => array('title', 'editor')
));

This might help someone,

add_theme_support('post-thumbnails');
add_post_type_support( 'my_product', 'thumbnail' );    
function create_post_type() {
        register_post_type( 'my_product',
            array(
                'labels' => array(
                    'name' => __( 'Products' ),
                    'singular_name' => __( 'Product' )
                ),
                'public' => true,
                'has_archive' => true
            )
        );
    }
    add_action( 'init', 'create_post_type' );
