Detailed Description

Manages image sources, ie.

SG, local media (USBs, CDs etc), import directories. A single SG device is opened on first use & never closed (no cleanup) . Imports are created by user & deleted when 'ejected' or FE exits, which cleans up thumbnails and imported images. Gallery scans local devices (MediaMonitor) whenever the UI starts. A local device is opened when first detected, closed when Gallery UI exits (to allow unmounting) but persists for subsequent Gallery use. It and its thumbnails are deleted by FE exit, user 'eject', system unmount or if it is no longer present when Gallery re-starts
