The PhotoCaption script is a site game which allows an administrator (or optionally, users) to upload a series of photos and then have players submit captions. Once the captions are collected, players get to vote to select the best caption. Game points are assigned for varying activities in the game, designed to encourage participation by all members. You can set the game to be fully automatic (cron access required) so the photos are moved along the stages at standard intervals.
Players? scores are computed and displayed for an administrator configurable sliding window -- this allows new players to join in at any time and catch up with the others. Members can easily view the winning captions from previous games and see how well their entries did, and who voted for them.
*New for v1.2.0*: A fully integrated User Management System. Even if your site does not have a login system to identify users, you can still run PhotoCap!
