The Math:
This rating system uses the ELO rating system where for each pair of images an expected score is calculated. The formula for the expected score is 1/(1+10^(image2_score-image1_score)). Then that score is adjusted with a factor and added or subtracted to the winner/loser respectively. The factor used here is 0.05.

If any photo doesn't show up correctly then please click on the little red triangle next to it and I'll look into it.
