ToDo:
Change Name to something better (PVC: Panchitas Viewing Center) (SYJIVB)
add a Jump to File option (J)
add support for other image types
add multiMonitor support
add sort by date
add saved setting, like default dir
add simple shell integration for windows and linux (kde and gnome)
add as screensaver for windows and linux
