Many members of my PLN have decided to participate in a 365 Challenge, taking and posting new photos at regular intervals.
Although some people choose to set up a unique blog for the project, I found it easiest to upload and tag my images in Flickr sets, separate ones for each calendar month and an additional set for the entire year.
If you're a blogger and decide to use Flickr for the Challenge, it's fun to add a badge to your site. Just go to the Make a Badge page and follow the simple directions.
"There are two types of badge to choose from: HTML or Flash. You will be able to select to display things from your own collection, one of your groups, or everyone's uploads. You can also filter any of these options by a tag, if you wish."
Be sure to tag your photographs and send them to your group(s). I also share my "picture of the day" on Facebook, Plurk, and Twitter.
