Google's neat-o Goggles app has just been updated to 1.6, and brings intelligent photo recognition to the table. What exactly does that mean? Well, I can't put it much better than the official announcement:
Let’s say that I’m going on vacation, and I decide to use my Android-powered phone as my primary camera. Goggles would identify landmarks, paintings and other interesting objects in my photos. I can share these facts about my vacation with my friends right from my Goggles search history.
In other words, Goggles is running in the background. You snap a picture, and Goggles recognizes it. The app will notify you that it recognizes the content of the picture, and attach that info to the picture in the Goggles app.
