Now you can vote for the images by thumbs up or thumbs down. We used to have a rating system from 1 to 5 stars. I hope that it will be easier to vote on images this way, so we’ll get more votes.
You vote by clicking one of the thumbs under the image. If you give a thumbs up to an image, it gets +2 and if you give a thumbs down, it gets -1. The total rating can be seen under the image.
We’re working on migrating the ratings for the old images to this new system. The ratings for the brand new images should be working as intended already.
