Just a few weeks ago Nokia released PhotoBeamer for Lumia Windows Phone 8 devices such as the Lumia 820 and 920. Today, the photo sharing app has been released for Lumia Windows Phones running Windows Phone 7.5 such as the Lumia 900 and 610.
Photobeamer allows you to display your pictures on PC's or other web-enabled devices. Just run the app, head over to Photobeamer.com, scan the QR code that appears on the screen with your Lumia Windows Phone and your photos will appear on that web-enabled device. It can be a computer, tablet, or a friends phone. You just need a 3G/4G network or WiFi to send the pictures.
