Reverse image search can be a good way to find more information about an object, animal, or person in a photograph. I use reverse image quite often when my daughters ask me about plants or animals that we see on our walks in the woods. To do that I take a picture and then upload it to Google Images.
When you conduct a reverse image search on Google Images Google tries to find matching images and pages that contain matching images. Sometimes it works well on the first attempt. Sometimes it doesn't work well at all. When it doesn't work well you can "help" Google by adding a couple of keywords to go along with the image that you have uploaded.
The process of conducting a reverse image search and adding keywords to it is demonstrated in my new video that is embedded below.
