Welcome to "Moving Image," our slideshow of the best photos of the week from around the world.
The following photos tell the story of the most compelling events this week, capturing happenstance moments and monumental occurrences with a single click. The images that stopped us in our tracks the past seven days ranged from Carnival preparations in Brazil to a swimming contest in ice cold UK waters.
Let us know your favorite photos in the comments section and check back next week to see new images.
This appears in Issue 33 of our weekly iPad magazine, Huffington, in the iTunes App store, available Friday, January 25.
