Google intros click-to-call in mobile ads, popular image search

Google recently announced two new features for mobile users. The first feature allows you to call any number that's inside a Google Adwords advertisement. This allows advertisers to measure how many people are calling directly from their mobile advertisements, and makes it easier for customers to get in touch with goods and services they find attractive.

Google also announced that popular images will now pop up on Google Image Search for mobile. If you navigate to www.google.com, from a mobile phone equipped with a full HTML web browser, and click "Images," you'll see a few thumbnails of popular ones that users have been viewing recently. The page displays popular images in categories like Trends, Movies, Sports, Cars, and more.
