Last week, we asked for your best action shots for the Mashable Photo Challenge. Our guest curator Zak Shelhamer picked a few of his favorites from an impressive array of submissions.
The images we received featured a range of heart-pounding activities, from sky-diving to mountain biking to snowboarding. We also saw photos of leaping kids and pets in mid-play, reminding us that action doesn't always have to be about being a daredevil. You can view all of the submissions here.
Check out Shelhamer's picks above and let us know which ones are your favorites. If you didn't get a chance to participate in this week's challenge, tune in on Thursday for the next challenge.
