LivePhoto is a very simple Express JS server that will automatically display photos to any connected browser as soon as the photo is taken with a digital camera. It utilizes an Eye-Fi card to send images to the server's file system, then sends the image URLs to clients via web sockets.
The entire creation of the project can be followed on this instructable.
To switch between localhost and the live server web sockets, change the uncommented socket connect line in livePhoto-client.js.
