From now until September 30, if you complete all 3 episodes of Yeti Vision on disneyeverest.com, you can receive a free 5x7 photograph of your ride aboard Expedition Everest. When you complete all 3 episodes, a voucher with a bar code will print out. You take this voucher to Animal Kingdom guest relations who will verify the authenticity and then hand you a coupon to use at Everest's merchandise location, Serka Zong Bazaar. You must have this coupon in order to receive the free photo. Just having the initial voucher will not be sufficient. That is not a bad little prize for playing an online game.
