Sony offers PlayMemories Online which is a cloud-based imaging service. You can log-in with an existing Sony Entertainment Network (SEN) or PlayStation Network (PSN) account and start uploading images for storage.
Please visit PlayMemories Online for more details.
PlayMemories Online also integrates better with PlayMemories Home (successor and replacement for Picture Motion Browser). PlayMemories Home offers the same functions as Picture Motion Browser with an upgraded user interface, so it is recommended to install PlayMemories Home (or to upgrade from Picture Motion Browser if already installed). PlayMemories Home also allows to use various photo sharing sites for direct upload of the images or movie files.
