using wp_get_image_editor with image url

Hello, i try to make the following:

$imgURL = 'https://localhost/wordpress/wp-content/uploads/2013/07/jul-13-hot-2560x1440.png';
$img = wp_get_image_editor( $imgURL );
if ( ! is_wp_error( $img ) ) {
    $img->resize( 500, 500, true );
    $img->stream();
}

All that outputs its :

The image “https://localhost/wordpress/?page_id=1685” cannot be displayed because it contains errors.

I assume that i must absolute path to work but i need to make it work with urls because that i retrieve from my slider option panel.
