Did you know there's an Earth Day flag? Surprisingly, the image that appears on this flag is world-famous; however, the photographer’s identity remains uncertain.

A man decided, as a personal challenge, to find an answer to this question and created a website dedicated to this research.

The identity of the photographer is unverifiable? I decided to take that as a personal challenge.

 When was the last revision of his website (format YYYYMMDD)?

This year, we are delighted to offer you challenges written by OSINT enthusiasts and professionals:

  • You will discover a new challenge every day at 12:30 PM (UTC+1).
  • Badges will be awarded to participants based on their success. To receive them, you need an account and must have badges enabled.
  • Points are awarded based on the time between the correct answer and the challenge release: less than 30 minutes 5 points, less than 1 hour 4 points, less than 8 hours 3 points, otherwise 2 points.
  • Challenge creators who also participate in the ranking will be assigned the average time of the TOP 10 for the challenges they submitted (symbol in front of their name).

Organization

  • Only four people know the answers to the challenges and are therefore excluded from the game: Céline Girardeau, Imaya Girardeau, Alain Godon, and Quentin Simier.
  • FR/EN translations are provided by Imaya Girardeau.
  • You can join the OSINT4Fun Discord server to chat with other players.
  • You can follow the live challenge solving on Quentin Simier’s channel KrowZ.
  • /Quentin also produces the video solution on OSINT4Fun. Videos will be uploaded the following day.

Update August 2025

Following the unification of the website, the ranking is no longer the one with points, which can still be found for example on the Wayback Machine.
