Did you notice, that you do not have to vote on every image you see? It was always this way: You vote and when you take a break, you will get the same image, you saw the last time. But now, when you vote, and you simply do not want to vote on an image (maybe since you feel, that you do not have any feelings about it, but others might), you can click on VB again and .... there you have another image to vote for. And my mother teached me: If you do not have anything nice to say, say nothing. Maybe this will end the pain people (like me) sometimes feel about the c-index.
