Google is now rolling out some of the new search technologies it previewed last week, including search by image and voice search on the desktop.

The features are currently only available via Google’s Chrome browser, but they allow you to search on the desktop by voice as well as drag-and-drop photos into image search for details on what’s displayed.

For voice search, Chrome users visiting Google.com will see a little microphone icon on the right side of the search box. Click the mic and a small box with the instructions to “speak now” will appear. You’ll need a microphone attached to your computer for it to work.

Voice-activated searches are already available on mobile devices like the iPhone and Android-based devices.
