Kodak recently upgraded its digital display – aka the “Smile Gallery” – on Times Square.

The screen is now networked and powered by Aerva’s Pic2Screen application, which allows people to email their pictures and have it show up on the huge digital sign.

The application accepts pictures via email to kodak@aerva.com with optional captions on the “Subject:” line. Users get immediate acknowledgement  of their image along with disclaimers about use of the picture on the display and criteria for acceptance.

The “Smile Gallery” at Times Square is part of Kodak’s year-long “It’s time to Smile” campaign which was launched in summer of 2009.
