Can anyone recommend a "Hot or Not" or "Rate Me/My Picture" type script?

Would really prefer one that is free (don't we all...) and possibly Open Source. But I guess it really all comes down to what will work best!

Thanks!

Ps. I've researched/looked at a number of these scripts already so the key word here is "Recommend". Would like a recommendation from those that have actually used the script(s) they recommend. Thanks!
