when the voting type is drop down and someone casts a vote, then the page gets reloaded. That is good.
When the page is reloaded then it jumps to the top of the page and the user has to scroll down in order to vote for the next image. That is bad.
Is it possible to reload the page at the position it was before? Or to automatically jump to the prior position after the refresh is finished? That would be very helpful.
I am sorry that i am adding so many items to your to-do list recently. I think that with a few changes you can make your plugin really great.
If you want to i can send you my version of the ngg-voting.php and then you have a german translation avaible.
