The goal of NeonView is to stay lightweight while also providing ease of use and only the necessary features a basic image viewer should have. NeonView supports a bunch of image formats, and it will remember settings like fit to window images between sessions or lock fit to window for the current session. Basic manipulation functions like zooming or rotating are also available.
