This tranquil image of elephants in Zambia's South Luangwa National Park has won top prize in the BG Wildlife Photographer Of The Year awards.

The competition, which annually attracts over 18,000 entries, is one of the most prestigious events of its kind anywhere in the world.

It champions amateur as well as professional photography; there is even a category for 10-year-olds and under.

The 101 winning and commended images from the competition will form the basis of an exhibition at the Natural History Museum in London, UK, starting this Saturday.

Just some of the winners are presented on this page.

Overall Winner: Angie Scott (Kenya)

African elephant family

Taken by the Luangwa River in Zambia's South Luangwa National Park. Angie said: "I had just got myself settled under a bush when this family came trundling down the sandy bank, eager to cool off and drink. A grey heron plopped down in front of them, ready to catch any fish they stirred up."

10 years and under - Winner: Maximilian Hahl (Germany)

Alpine Ibex

The image was captured on Gemmanalphorn in Bernese Oberland, Switzerland. Maximilian said: "These animals are so used to people walking by that, if you stay calm and still, you can sometimes get to within a metre of one."

11-14 years old - Winner: Fanie Weldhagen (South Africa)

Black-backed jackals

The picture was taken in the Kgalagadi Transfrontier Park. Fanie said: "A single male got up and started paying a lot of attention to a female. Her mate didn't like it at all. He growled, and the two males had a short fight. Then the single male had to leave."
