PhotoLetteris a private gallery (or photo portfolio), using your own server. The idea is to share in private, to the target user or group, images that are in your own server. You can share images, in private, to your family, friends and receive the feedback. This is also great app for commercial use. For example, if you are a professional/amateur photographer, you can use the app to show the images and give the client the opportunity to choose the photos or comments (using the mail feature inside the app) before paying for them. We can also use the app to build one portfolio (professional painter, photographer, artist, etc) to show the work to clients.
