Vote on image vs image

Hello.

I a looking for a plugin that would show 2 images next to each other, and you can vote on one picture. Then it would keep score about those two images only. Let’s say it’s Iron Man vs Superman. You can then vote on Iron Man, and Iron Man – Super man would then be 1-0. I have tried out PicSmash, but that only store the total amount of votes on Iron Man or Superman. I need to keep track of every <pair> of images.

Thanks,
