The latest versions of the Windows image viewer presented a huge step forward, which was long due on an operating system that is ever more widely used to manage image files. Nonetheless, this viewer lacks important customization features that make it lose part of its appeal, particularly for those who work with a huge number of pictures every day.
In order to fill those needs, there are other more comprehensive alternatives, such as FastPictureViewer, a free application for viewing images that stands out for its looks, similar to the latest version of the viewer in Windows, and for its reduced consumption of resources.
This viewer is ideal as a default image viewer. FastPictureViewer also includes a great number of additional benefits and features that set it apart from other viewers; for instance, it includes editing features, a library organizer, it lets you import pictures from other devices, it supports 4K screens, and it can even convert files between dozens of different formats.
