Google Image Tagger

Google has been registering some new domain names, and amongst those are googleimagetagger.com/net/org.

For the moment we can but speculate what sort of service this might be - whether the images are tagged automatically (such as face and object recognition via Neven Vision provided technology?), or manually as in the widespread tagging at flickr. Up to now, Google has tended to avoid "tagging" at least in name - though Gmail labels are close, and Picasa's keywords share some similarities.
