search by image find people with their image

Google Reverse Image Search helps you quickly discover visually similar
images from around the web. Upload a photograph from your desktop to
Google Images and it will show you related images used on other websites
and also different sizes of the same photo almost instantly.

Journalists can use the reverse search option to find the original
source of an image or to know the approximate date when a picture was
first published on the Internet. Photographers can use ‘search by image’
feature to know about other websites that are using their photographs.

Google’s ‘search by image’ feature is only available for desktop
computers and not on mobile devices and tablets. Thus, if a friend has
sent you an image on WhatsApp or Facebook that you’d like to verify,
you’ll have to first transfer the photograph to a desktop and then
perform a reverse search. Too much work, right?

Not anymore. Meet Reverse Photos, an online tool that lets you perform
reverse image searches on mobile phones. Go to reverse.photos on your
mobile phone, click the “Upload Image” button and choose an image from
the photo gallery of your phone. Next click “Show Matching Images” and
it will feed your photo into Google’s image database and show visually
similar photos.
