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 a snapshot of a violet lightning storm to children riding a retro train in Taiwan.
Let us know your favorite photos in the comments section and check back next week to see new images.
This story appears in Issue 59 of our weekly iPad magazine, Huffington, in the iTunes App store, available Friday, July 26.
