If I have done my initial voting and I want to raise some photos up to a higher score later on, at the moment I have to do it one by one, which takes a long time (and even longer for modem users I expect!) So how about this:
A checkbox next to the thumbnails. You select the photos that you want to increase the score of, then scroll down and click a "Bump Score" button which moves their scores up one position. There could also be a button to lower the scores by one position.
Alternatively there could be a "Change score to:" button, with a drop down menu with 1 - 10 there, so you can choose their new score.
