If you plan to check out ImageGlass and use it for yourself, just be aware that it is strictly an image viewer and it does not offer editing tools to use with your images. Lastly, the settings menu is where you can configure options like file associations, rearranging the toolbar, and set color profiles, to name a few. ImageGlass boasts easy customization with the use of language packs and themes to change its looks. Keyboard shortcuts are available to make it easier to browse and trigger certain actions with the use of key combinations. It shows the name, file path, resolution. The titles bar contains various useful information, as well. Over to the right side, you then get options for a thumbnail overview of images, enable a checkerboard background, and start a slideshow. From the left, there are basic actions like scrolling through, rotating, and zooming in on images. It has a clean user interface design and features a handy toolbar at the top, with all of the available options, easily visible and accessible. If you deal with a large number of photos, Visum Photo Viewer will make it easier to find the ones you like without dealing with lag and slow loading speeds.ImageGlass is a fast and lightweight image viewer that supports more than 72 image formats, including PSD and RAW. It doesn't have a lot of frills or powerful features, but it delivers a clean interface for browsing through images.

Visum Photo Viewer focuses on its namesake, viewing photos. It's definitely worth a try, especially since it's free. I preferred Visum Photo Viewer over the Microsoft Photos app for my workflow, which consists of browsing through hundreds of photos to pick out a few that I like. But it's called Visum Photo Viewer not Visum Photo Editor, so its feature set isn't surprising. You can only perform basic image edits, and the app lacks a video editor, even for trimming content.

Visum Photo Viewer is light on the editing side of things. Its design is easy to navigate, and you can customize the interface a bit to fit your liking. It loads photos quickly and allows you to browse through galleries without bogging down your machine.
