GPicView is a simple and fast image viewer with low memory usage. It's aimed at replacing the default image viewer of current desktop systems. Fast startup, low memory usage, and a simple user interface make it a good choice for a default viewer. It is extremely lightweight and fast with low memory usage, has a simple and intuitive interface, minimal library dependencies (only GTK+ is used), and doesn't require any specific desktop environment. It was inspired by the Windows XP image viewer and gimmage.
