I\'ll lend some of my thoughts on this, culled from my own experience.
When I come across a truly horrid image (3\'s, etc) I usually just close the window rather than vote it down further. Or I close it to remove such a sight from view of my eyes. And thus ends my random bouncing from image to image.
On the opposite side of the spectrum, when I come across an amazing image (9.0+) that has thousands of votes, I don\'t bother voting as a single vote at that point really doesn\'t do much beyond adding to the vote tally. I\'ll pause to wipe the drool away, then close the window. And thus ends my random bouncing from image to image.
Otherwise, if I see an image that seems to be unfairly low in score, I\'ll vote. If I see an image that seems to have an unfairly high score, I\'ll vote. If an image strikes me in some manner, or makes me pause, or makes me think however briefly, I\'ll vote. All of these cases, I dwell on the figure and try to give it a fair rating.
Even if the image is mediocre, I\'ll vote just to move on to the next one, but there\'s very little in the way of actual critique in such a vote.
I don\'t think I\'ve ever given a 1, however, and I only rarely, rarely give a 10.
Conversely, I have a friend who is much more black and white about choices. If he likes it, he gives it a 10. If he doesn\'t like it, it gets a 1. His expectation is that *everyone* is voting and therefore the ratings will even out over time. I don\'t really agree with this method; it seems pretty extreme, but I really wouldn\'t be surprised if a lot of casual browsers do this.
