RO-Viewer Portable

Images represent a pretty common type of file nowadays, especially since you can take shots even with a mobile phone. Needless to say that you might want to go through all your collections at a certain point, task accomplished with a dedicated viewer. In case you’re not really fond of what Windows has to offer, you can rely on RO-Viewer Portable.

Browse through the built-in navigator

As the name clearly points out, the application doesn’t take you through a setup process to function, so you can have it stored on a thumb drive in case you want to use it as your personal image viewer even on other computers. Note, however, that .NET Framework needs to be installed on the target PC.
The interface is split into a couple of sections. One of them is where preview is shown, while the other offers comfortable navigation through directories and files. Although there’s no search field, you can definitely rely on the side panel to identify picture directories.

Adjust scaling and switch to a full screen mode

There are several scale modes which directly affect the image preview. An image can be scaled to show all content, vertically, horizontally, or upscaling. For a better view, you can even switch to a full screen mode, but the application doesn’t come with a slideshow component, which is a little disappointing.
By default, the application shows the preview of a single selected image, letting you navigate through the selected folder. Additionally, you can switch to a thumbnail mode to get a better glimpse of target images. The preview background can be changed to make it suit your style, and a picture can be set as wallpaper from the context menu.

To sum it up

All in all, RO-Viewer Portable is a pretty straightforward image viewer. It comes with a comfortable directory browser for easy identification of images on your computer, while the set of navigation controls make it worth your while overall, despite the lack of a slideshow player.
