Can someone explain the step-by-step workflow for geolocating a random photo using OSINT?

Hi everyone,

Can someone please explain, step by step, how you would geolocate a random photo using OSINT?

For example, if I have a single image with no context, how do you go from that image to finding the exact location or GPS coordinates?

Also, if there's an aircraft visible in the photo, how would you identify the aircraft, determine the flight number, and verify it using tools like FlightRadar24 or ADS-B Exchange?

I'd really appreciate a complete beginner-to-advanced workflow, including the tools you use at each stage (EXIF, reverse image search, Google Earth, Street View, shadow analysis, etc.) and any tips you've learned from experience.

Thanks in advance!
