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^(score1-score2)). Then that score is adjusted with a factor and added or subtracted to the winner/loser respectively. The factor used here is 0.05. The expected score is the same as the odds of one photo beating the other. If the score difference is 1 than that means that the higher ranked photo is expected to win 10 times more often.
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. For any other kind of problem then please contact me. For contact information see below.
