I am in the middle of setting up some new logic for future contests where members cast their vote on the photograph they like. This will eventually be used to host contests where possibly a select group of participant could purchase entry into a contest with the contest fees going towards the prize itself.

To enter a contest, simply place your photo in an active contest category.
To vote on a photo, click the red Vote icon in the bottom of a thumbnail. Or click on the green Vote button when viewing an individual photo.
The leading photos with the most votes are shown at the top of the Contest category page.
