With the announcement at the Inside Search event, Google confirmed two new services Search by voice(which was expected, as Google had said earlier that newer Chrome versions will support it) and also Image search. Search by voice is similar to what Android phones had to offer. The feature is now rolling out to users at google.com.
The search by image feature allows you to drag and drop images or type the url of the image to get search results out of it; also with a chrome or firefox extension, you can just right click on the image and click "search Google with this image".
