[Plugin: NextGEN Gallery] Show original image in Widget

I’m writing custom widgets to use on page templates. I need to display the original image, not the thumbnail, and I can’t seem to find the code for that. I know I need to change $show = ‘thumbnail’ to something else for the original image, but nothing appears to work.

Here’s what I got. All it does is display a distorted version of the image thumbnail:

function nggFilm( $id ) {
	$number = 3;
	$width = 200;
	$height = 150;
	$exclude = 'allow';
	$show = 'thumbnail';
	$options = array(   'title'    => false,
						'items'    => $number,
						'show'     => $show ,
						'type'     => 'random',
						'width'    => $width,
						'height'   => $height,
						'exclude'  => $exclude,
						'list'     => $id,
                        'webslice' => false );

	$ngg_widget = new nggWidget();
	$ngg_widget->widget($args = array( 'widget_id'=> 'sidebar_1' ), $options);}

Thanks in advance!
