As part of public testing, Bing home page and search results page usually feature lots of new tweaks and features for limited set of people. Yesterday, I noticed a new feature in Bing home page that allows you to know more information about the Bing home page image of that day. As you can see above, there is an information icon just before download button. When you click it, you are provided with more info about the photo as shown above.
Did you find this feature on your Bing page?
