How Do I Vote On a Photo?

Choose the contest and start voting in the Photo Trifecta. You can also click on the View Gallery link in the bottom left-hand side of the Trifecta. This link will take you to the contest gallery and you'll be able to browse all the entries and choose the photo you wish to vote on.
