Saturday 19th August is World Photo Day 2017 and it's your chance to make a difference to the world with your photography.
World Photo Day was created eight years ago by Korske Ara, a photographer from Canberra in Australia. More than 250,000 people are now registered to take part, and you're invited to share your world with the world. You'll also help raise funds for organisations that make a positive change in the world through work in our communities.
You can also join the photography competition, for a change to win prizes. There are six categories: Street/City, Landscape, People, From Above, Animals and Wildlife, and an Open category. Get inspired by a gallery of preview entries and the stories behind the photos, and follow the latest from World Photo Day on Facebook and Instagram.
Register here to take part, and you can choose from one free single competition entry, or up to 12 entries for a maximum of $25 AUD (around £15).
August 19th is also World Humanitarian Day: a day organised by the UN to recognise the value of aid workers around the world, especially in areas of conflict and crisis.
