Just curious: what do the numbers with the images mean?
If the one in brackets represents the number of votes for that image, what does the number before the brackets mean?
The short answer is:
The X.XX numbers are the points
The (XX) numbers are the number of votes
The long answer from ADMIN is below:
You can vote as many times as you like, but only have one voting point.
If you vote for multiple photos, your voting point gets divided across them all.
You see a photo you like and you vote for it. That photo now has a score of +1 point from you.
Later on, you see another photo you like and you decide to vote for it too. At this time, each of the two photos gets a score of +0.5 from you.
If you vote for yet another photo, then the three of them will get +0.33 points each from you.
And so on. The number of votes is only limited by the number of photos in the contest.
The rating of a photo is calculated as a sum of all points received from all users.
You can also revoke your vote for any photo at any time. Doing so recalculates your vote share.
So if we continue with the example above (you voted for three photos) and you decide to revoke your vote for one of the photos, then the two remaining photos would get +0.5 points from you added to their scores.
Such system allows you to "change your mind" in case some new photos get uploaded for the contest and you decide not to spread your voting power too thin. If the contest's settings allow it you can begin voting right away while keeping track of new photos added to the contest.
On the ratings page, each photo's rating is shown as two numbers like "4.5 (7)" -- which means the photo in question has a total of 4.5 points based on votes of 7 users.
To sum it up, you can vote for any many photos as you like. But your voting power gets spread across all photos for which you vote. So each photo gets a smaller bump in the score. On the other hand, more of the photos you like get a chance to be at the top of the contest.
