Reverse Image Search.

Reverse Image Search, a powerful tool! 

Reverse Image search.
You can search for a picture if it already exists on the internet or not.
For that, there is a handy tool named RevEye Reverse Image Search.
It is an add-on you can integrate with Chrome or Firefox.
You can find a link to RevEye  on this page

When you want to inspect a picture, click with your right mouse in the picture, you see the addon in the menu.
You can choose All search engines, but I prefer to choose one by one.
The best results I always find in Google, Yandex or Bing.

All search engines have their own results.

Bing has another function that can be very powerful.
First, choose Bing to reverse the image.
As in the example, there are no results, but Bing has the possibility of Visual Search

You can choose Visual Search and crop the image, and see how the results are!!

Yandex had a good tool also, it can read text from a picture.  Choose Translate and translate it in your own language.

BUT… now you have a picture and want to upload it to the internet to see if it exists or to search for the location.
Search engines Google, Bing, and Yandex give you the possibility to upload your picture.

Google: click on the photo pictogram

Choose to Upload a photo, choose a picture format file

See the results. You can also change the name in the search box if you are not satisfied with the results.

For Yandex same method.

And for Bing:
