Sometimes when you are searching for a particular topic, you want to see the most recent images for that subject. For instance, you might want to find images related to the recent Masters Golf Tournament. Searching Google Images will give you a lot of images related to the Masters, but it is hard to quickly tell which pictures are from this year's tournament.
In this matter, Google Images with Date Annotations has been introduced that should make finding recent images a lot easier -- Now, Google will add date annotations right to the thumbnails of images that were uploaded recently.
Try it out on any recent news or event query, such as the Master's Golf Tournament or Charl Schwartzel winning that coveted green jacket.
