You most likely think of searching on Google with words, but did you know that you can search via picture on Google Images? Since we know that the images you want to search with come from different places on the web and your computer, there are four ways to Search by Image:
1. If you have an image you’ve found on the web or your computer, drag and drop an image into the search box.
2. When you have an image saved to your computer, click the camera icon, select “Upload an image” and pick the image you’d like to use.
3. Say you see an image on the web and you want to know more. Just right-click the image to copy the URL. On Google Images, click the camera icon and “Paste image URL.”
