The Facebook application for Smart TV allows you to log in to your Facebook from your TV and view your photos. However, navigation via the TV's remote control is not very comfortable. If you have an Android or Apple phone/tablet, you can use it to display your Facebook photos on the screen of your Smart TV and navigate using the mobile devices.
All you need is to install the iMediaShare Lite application on your mobile, in order to share multimedia content with other devices connected to the same WiFi network. For this it uses the DLNA protocol.
