How to make people vote on a photo contest


I'm in a new project. It's for a Photo contest. The thing is that I belive that the Post Voting Plugin could be used to let people choose the nicest one (only one) among a quantity of photos displayed.

Two questions there:
Which theme would you recommend to do this?
And, how could we connect each vote to a facebook page, to notify in the facebook wall which photo is voted?

If you know of any example to show my customer, that would be helpful.
