Updated Google Goggles now searches every picture you take when you opt-in
Using the camera on your Android phone as your main "shooter" during a vacation, you can find out many interesting facts about places you visit, or the sites that you see, all of which can be shared with your friends using your Goggles search history. To opt-in and allow Google Goggles to search all of your pictures, first you need to open the app. Once that is done you tap on Menu, hit Settings and click on Search From Camera.
For those who never downloaded the app, you can do so now for free from the Android Market.
