For those interested, the Wikimedia Commons Picture of the Year 2010 competition has opened; as in the previous years, the Picture of the Year will be chosen from all the pictures that were awarded Featured Picture status that year.
Find out whether you can participate here (the short version: you need to have registered a Wikimedia user account and made at least 200 edits on a single Wikimedia project (e.g. any Wikipedia edition) prior to 2011), add yourself to the list of voters, and once the bots have verified you're eligible, vote!
Here's the winners from the previous years, too:
The Wikimedia Commons also recently passed 10 million files, and apparently will pass 10 terabytes soon, although I think that figure does not include deleted images, earlier versions of current images etc..
