It's 80 years to the day since the first known photo claiming to show the Loch Ness monster was taken.
The snap, which appears to show a large marine reptile splashing about in the water, was grabbed by Hugh Gray as he walked along the loch after church on 12 November 1933.
The picture, which we have included in a gallery of famous Nessie images above, has been credited with igniting popular interest and belief in the creature's existence.
This has included the making of Hollywood movies and the extensive searching of the loch by experts for any sign of Nessie.
Several other pictures purporting to show the mystical creature have been taken since Gray's image - each of which has been scoured for clues.
One of these, taken in 1934 supposedly showing the monster, has perhaps come to define Nessy in the public's imagination.
