Flickr launched a new feature they call People in Photos a few hours ago, on October 21, 2009. It lets you tag people in your photos or in your contacts’ photos. I guess it was only a matter of time before this happened. While Riya and iPhoto went the route of computer-aided facial recognition, which is a pretty cool feature indeed but processor-intensive, Facebook and now Flickr have gone the more low cost route of letting members manually tag people in their photos.

At any rate, the process is easy and real-time. You start typing in some identifier for a person you want to identify in a photo, such as a name or screen name or email address, the database of members is searched live, and you’re presented with a drop-down list of people that narrows down with each letter you type. Pretty cool. Flickr also went the extra mile and included the ability to let you determine who can add you to photos, and who can add people to your photos. Very nice touch there.

I added my wife and myself to a couple of photos where we appear, and took the following screenshots to show you what the new feature looks like. The only reason I noticed it is because I logged into my Recent Activity page a few minutes ago and saw a small change in the options, as you can see below.

The option to add people to a photo is located in the sidebar, below the photostream and groups thumbnails and above the tags.

As soon as I got done tagging my wife and I in the photos, I got an email from Flickr where they explained the new feature to me and allowed me to set the privacy options I mentioned above.

Like I said, pretty cool implementation, user-friendly, too, and it was something that was bound to happen sooner rather than later. There’s also a post on Flickr’s official blog announcing the feature launch.

What I’d like to know now is if Flickr can read the iPhoto person tags and somehow match them up with Flickr members, so that photos uploaded to Flickr from iPhoto get people-tagged automatically. Or is that the next step down the road?
