We usually look for stuff online using words.  But you can also search using images. This allows you to start a Google search using any image on the web. Researchers 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.

Possible scam victims can use it to see if the picture, for example, is of a D list celebrity, a porn star or some random person who lives in central London, has a cat and works in a bank.  Reverse image search isn’t fool proof. It won’t stop an experienced scammer, but it is worth spending a few minutes seeing if there are the same or similar pictures online.

When using Chrome, choose a picture you’d like to check out. Using your mouse or touchpad, ‘Right click’ this image, and choose ‘Search Google for image’.

If the picture you are wanting to check out is in an app on your phone, take a screenshot. This quickly saves what’s on your screen, including the picture. If the app allows it, open up the picture to get the full image.

Upload a photograph from your desktop or your phone to Google Images and it will show you related images used on other websites and also different sizes of the same photo almost instantly. Use your common sense to work out if the results suggest something is amiss or incorrect.
