 * The DCIM is a special FileSystem lister
 * in the that it starts with an overview
 * of available 'Cameras'. It looks via 'Storage'
 * for paths including a 'dcim' directory.
 * And offers these as folders.
 * Then it only lists Images. It tries to use
 * the 'preview' directory to generate a thumbnail
 * but will use the full image for the QImage
 * call.
