I, always wondered that, is there any way to search by using image, at that time there was only one way
But the search results provided by it were limited, but recently Google made an attempt to provide this facility, through which you can use both your own photos and images from the web to begin your search on Google.
When you search by image, you’ll see results that show you where that image, and similar images, appears on the web. We'll show you to web pages that contain that image, or find the same image in different sizes or resolutions.
