Use facebook to vote on pictures on website

I am planning on making a website where there will be a couple of photo's on it on which people can vote.

I would like to want to use Facebook for voting, so that on the website the user chooses his/her favorite picture and when he votes, he will start a facebook application so the user is identified. His vote will be stored in my database, together with a userid, so he can't vote twice. User can choose to update his wall with the vote.

I know this is possible, and I know how to make facebook apps. However I don't seem to find a way to make this accessible from the website.

So the short question: How can I create a facebook application that will be开发者_JAVA百科 called from a website and gives a signal back after adding the vote to the database?

Thanks

You have to put the whole process into your Facebook application, which means that you have to put the images in the app too. It's the only way to get a callback on the user votes. Have a look at some vote your style apps in Facebook which are working the same way.
