Hide voting results in ratings

Hello, i would like to hide voting sumary in ratings plugin.
This is going to be use on a small foto contest, and i don't want to people see the results before end of it.
After contest end i would like to turn it back, that peoples who participate in this can check results.
i would be very happy if someone could help me with this.
edit:
i think that i've found solution. In file gallery3/modules/ratings/vendor/ratings.php i've comment lines between 126-132 and it's looks like it's works
