The first thing you should do is just try searching for the file in the Yandex.Images service. In my opinion, this is the best service in the world for reverse image search.
Sometimes it is quite enough to answer the question, "Who is this? #yandex
(These bots are constantly appearing, then disappearing. Their current list can be found in the global #Telegram search for "face search", "face match" etc.)

Also, you should not neglect other services to search for pictures. For example:
- live maps (weather, fire, clouds)
- historic maps (worldwide, countries, towns)
- local conflicts and disasters maps
- satellite maps
- ability to upload your own maps
If you look at a person's history of posts on social media, you can gather a lot of interesting info about them. One of the simplest way to automate this:
Save the feed of posts in PDF (using the Ubikron ext or others)
Process PDF with different online tools (summarize etc)
A repository with text files containing a million dorks for finding potentially vulnerable web pages and sensitive data (in Google and other search engines).
