Hey there, awesome plugin.
I'm using it on pages only, in conjunction with NexGen photo gallery. Each individual picture gets its own discrete url/page, and the stars are displayed below it.
My problem is that the votes are not "per page." I tested by voting on one page, then found that every other page had my one vote showing. I'm the only one voting as the site is not live yet. So, now every picture (out of around 200) has one vote, even though I only voted once.
