If a player has uploaded a photo that you do not feel answers the photo question correctly you have the ability to reject the photo and take away the points they earned for the uploaded photo.
To view Photos an individual player has uploaded, click the photos icon for that player. This will show you all the photos they have uploaded along with which question they uploaded each photo for. For each photo you will see a green “Accepted” button. To reject the current photo you are viewing click the green “Accepted” button so it turns red and says “Rejected”. By doing this it will also take away the points the player earned for that photo upload.
