Technology helps soldiers stay in touch with loved ones while deployed far away and, for one New York military couple, it also helped them spread Christmas cheer to their families and friends.

Christina Perdue, of Westchester County, used an iPhone app to create a Christmas card featuring her and her husband, Sgt. Daniel Perdue, despite the fact that he is half-a-world away serving in Afghanistan.

In the photo, posted by Christina on her Facebook page, Sgt. Perdue is on the left, dressed in his Army fatigues in Afghanistan, while Christina is on the right, dressed in a Santa hat and standing in a snowy Westchester County.

The couple, married since 2010, is holding a sign that says, "Merry Christmas."

"We may not get to be together for the holiday but we still manage to come together with our holiday photo," Christina wrote on Facebook.

Christina told local ABC affiliate WABC that she mailed the board with the Christmas greeting to her husband, told him exactly where and how to pose for the picture, did the same herself back home and then used an iPhone app to combine the two photos.

"Our family loved it, all our friends love it, everyone has been sharing it all across the Internet," Daniel told WABC via Skype from Afghanistan.

"We just wanted to show that no distance can get in the way of love and we wanted to show the support of our brothers and sisters in arms, and that nobody forgets them this holiday season," said Daniel, who is scheduled to return to the U.S. from this, his third tour of duty, in January.
