By "rated" do you mean "How do you get your photos on the Most Popular page"? Well, that is determined strictly by other members' votes. Click on any photo and when it comes up on your screen you'll see a place where you can vote for it as "Hot". The photos getting the most "Hot" votes make it to the Most Popular page.
So the bottom line is, submit good photos if you want to be on this page.
