Can you depict love in a single photograph?

National Geographic is giving members of its "Your Shot" community a chance to do just that. It's part of an ongoing effort in which the magazine selects a theme and asks readers to submit their photographs online. The current assignment is to take a "Love Snap" photo. Readers have until March 7 to send in a picture depicting their idea of love -- and the submissions so far are already tugging at our heartstrings.

"We challenge you to go beyond the saccharine-sweet clichés," National Geographic writes in the assignment's instructions, "and show us the intimate and personal aspects of your ideas on love."

You can view some of the incredible photographs below, and head to Your Shot to submit your own.

What's more precious than capturing the love of mother and children in one shot? Priceless moment.

On the banks of the Ohio River, the Kentucky side, I watched as the shifting ice, momentarily formed a heart ringed in blue.
