From TechCrunch:

Its new “People In Photos” feature is long overdue. With it, you’ll be able to select a picture and start typing a person’s name, which will then scan your Flickr contacts to see who it should add as a tag to the picture. And like Facebook, you’ll be able to draw an outline around someone’s face to show exactly who they are in the picture.

You also have the ability to opt-out of any picture you’ve been tagged in. You can also tell Flickr who you want to have the ability to tag you. Or even opt-out of being tagged altogether. Currently you have to use your Flickr contact list, which is probably not as robust as your Facebook friend list.
