DEERFIELD, Ill. — Walgreen Co. has released new photo functionality in the latest updates to its iPhone mobile application.

The drug chain said Wednesday that its iPhone app enables users to create photo cards with special themes such as thank you, holidays, announcements and invitations, as well as create photo collages directly from their device.

Walgreens noted that it’s the first retailer to provide the ability to create collage prints using a mobile device and pick them up in about an hour.

Photos for the collages can be uploaded from the user’s phone, Facebook or Instagram albums.

"We’re pleased to provide more creative capabilities to our users as we continue to enhance the photo functionality within our mobile app," Jasbir Patel, divisional vice president for daily living, photo and omnichannel, at Walgreens. "Consumers are accustomed to using their mobile devices in nontraditional ways, and Walgreens gives them easy access to products and services, wherever and whenever they choose."

For customers on the go, the updated app allows users to search for Walgreens or Duane Reade stores based on offerings such as 24-hour locations, drive-through pharmacies and Healthcare Clinics at selected Walgreens locations. The app also provides improved virtual floor maps allowing for easier access to products and better in-store experience, the retailer added.
