Automated ballot

Hello all and thanks for looking,

I am running an on-line photo contest and was wondering if there is an automated ballot/ poll program I could use to tabulate the results?

I need the results to be hidden until the ballots are closed and double vote protection. Any suggestions?

Thanks,

Try sourceforge.net or maybe zend.com Both sites have great scripts (PHP) you can use for free. If you can't find what you need, its pretty simple to set up a voting system using PHP/MySQL.
