There have been many sightings of the legendary Nessie, the most famous being in 1934, but the picture taken proved to be a fake.
The legend of the creature dates back to the 6th Century, when a water-beast is said to have appeared before a saint.
Greyish colour
These latest pictures, taken by 63-year-old Roy Johnston, show a creature breaking the surface of the water of the Scottish loch last month.
Mr Johnston said, "It was a black, greyish colour but I couldn't see a head."
It's the fifth suspected sighting of the shy wee beastie this year!
