There are a few different ways that you can reverse search an image on Google.
The first way is to go to the Google Images website (images.google.com). Then, click on the little camera icon in the search bar. This will allow you to upload an image from your computer, or paste the URL of an image from the internet. When you do this, Google will show you a bunch of similar images, as well as websites where that image appears.
Another way to do a reverse image search on Google is to right-click on an image (on a website or otherwise), and select “Search Google for image.” This will open a new tab with the Google Images results for that image.
You can also drag and drop an image into the search bar on Google Images.
Finally, if you’re using the Chrome browser, you can install the Search by Image extension. This allows you to do a reverse image search on any image by right-clicking on it and selecting “Search Google with this image.”
So those are a few different ways that you can do a reverse image search on Google.
