[Plugin: The Attached Image] Is it possible to use conditional code with this plugin?

Is it possible to use conditional code with this plugin something similar to:

<?php If ($the_attached_image !== '') { ?>
<?php the_attached_image('img_size=medium&title_link=none'); ?>
} else {
echo '<img src="/wp-content/themes/platform/img/nopostimage.png" alt="" title="" />';
	}
} ?>

Thanks.
