You know Google's Search by Image feature? Well, Bing now offers the same functionality -- albeit more than two years later. Microsoft's search engine will now let you search for a particular picture, as Google has been doing since mid-2011. While Google's Search by Image works by dragging and dropping a photo into the text box, Bing's version uses an Image Match button to pull up different sizes for a given picture. It's definitely a useful feature, especially if you need a particular resolution or are looking for a particular source. Better late than never, Microsoft, but you certainly are tardy on this one.
