这实际上非常简单......

function create_thumbs()
{
    $this->load->library('image_lib');

    $path = "path/to/image/";

    $source_image = "original.jpg";
    $medium_image = "medium.jpg";
    $small_image = "small.jpg";

    // Resize to medium

    $config['source_image'] = $path.$source_image;
    $config['new_image'] = $path.$medium_image;
    $config['width'] = 200;
    $config['height'] = 200;

    $this->image_lib->initialize($config); 

    if ( ! $this->image_lib->resize())
    {
        // an error occured
    }

    // Keep the same source image

    $config['new_image'] = $path.$small_image;
    $config['width'] = 50;
    $config['height'] = 50;

    $this->image_lib->initialize($config); 

    if ( ! $this->image_lib->resize())
    {
        // an error occured
    }
}
