The contest looks like the World Cup, there are semi-finalists who win $ 100 USD, finalists who earn $ 10,000 USD, and a winner who gets ONE MILLION DOLARS, this is how it works, for example: you pay a dollar and you upload a photo, you will be in a group of 1,000 photos (First Level), invite all your friends to vote and if you win in that group, you become a semi-finalist and win $ 100 USD, and you will automatically enter to another group against 500 photos (Second Level) with the same rules, the vote is public and you have to invite all your friends to vote for you, and if you do, and win, you will get $ 10,000 USD, and now you will be a finalist and will compete against 9 other people (Third Level) to win THE MILLION DOLAR Prize.
Of course, you can put all the photos you want to have more chances to win.
