“Our customers like to be creative with their photographs,” said Deborah Whitman, vice president of product management for Digital Imaging at Adobe. “Both professional photographers and amateur photo enthusiasts like the ability to explore fun and innovative ways to share and showcase their photos. Working with Stamps.com adds another dimension to digital image expression right within our Adobe Photoshop Services line-up.”

Through this integration users will be able to edit their digital images and then seamlessly transform them into PhotoStamps. The Adobe applications are also Web-enabled so that users can see the PhotoStamps Web pages from within the program.
