iPhoto has been updated to include two new features called "Faces" and "Places." I think you already guessed “Faces,"! … Similar to Facebook, you can now tag photos of your loved ones, and IPhoto will even attempt to match the faces in other photos in your library. “Places” come with an ability to import location of photo information from a camera that supports GPS or an iPhone. And if you want to assign a location to a photo or event manually, you can do that as well. As always, it's easy to edit photos with iPhoto.
Moreover, iPhoto allows you to publish your photos onto your Facebook and Flickr account. Photos published on Facebook can be given names along with name tags, which can be synchronized with iPhoto. Awaken the artist in you and create a rendered slideshow, which can then be played on Mac, iPod and iPhone. It is also possible to produce a nice travel book that includes custom-built maps of your intended journey.
