Google has revamped Google Image search results and implemented a new carousel style user interface making it much easier to navigate. Gone are the days of viewing the full resolution image and having to go back to the results to see the next one; here are the days of simply swiping to the next full resolution image! Need more information on a particular image? Not a problem as all you have to do is tap the link in the lower left corner and the site begins to load. From the outside it looks exactly the same, but the new functionality is another page in Google's redesign book.
