And well done!

@unimaru_ Thanks for your answer. Yes, I know. As a result of your answer I checked and found that the Yandex image search extension that I use gives other (in this case less useful) results than uploading to the website. The extension only showed other results. I should look more closely. :-)

@Michael.
I found this on the Yandex reverse image search. I think Yandex is more powerful than Google in terms of image search.

Just wondering how you found this.
