WP – Post Ratings

I’m using the WP-PostRatings for my WordPress. I’m want to know how to get only the stars (images) to appear. I don’t want any of the text to appear where I want to put this.

It is ok as it is (with image and text) for me on the sidebar and the single.php, so I don’t want to delete the text completely.

I’m just looking for the function where only the image appears.

For example,

<?php post_ratings_average(); ?>

where post_ratings_average will get the average images of the stars only.

The above codes doesn’t work, I just made it up, but what I’m looking for should be similar to that.
