A photojournalist’s photo is like a snapshot in time, capturing the essence of what was once alive.

But what is an image, and how can you get one?

The following is a list of images you can obtain for free from The Wall St. Journal’s Photo Reflexes program.

They range from a rare photograph taken at a remote farm in Alaska to a stunning sunset on the Atlantic coast.

Some have never been released to the public before, and some are only available in digital form.

This list is not exhaustive, but it should serve as a start.
