Virgo searches for image files in Input Directory and move them into Output Directory. Inside their destination, image files will be sorted by precise time and renamed in ascending order, i.e. 001.png, 002.png, 003.png. Options are: 1. Move images further into sub-folders of Output Directory. The sub-folders imply the creation date of those image files, in the format of YYYY-MM or YYYY-MM-DD; 2. Customize output file name, i.e. Paris 2014-12-31 001.jpg..
