RandomSlide

Using the tools Windows puts at your disposal, it is not possible to create a slideshow with images stored in multiple subfolders. Since users often organize their pictures in this manner, this can prove to be an issue.

RandomSlide is a relatively simple open-source program that can provide you with a solution. It enables you to start slideshow using random images from any number of subfolders, and it is very easy to set up.

This application should be a great choice for users who organize their image collections into numerous folders, as you can just select the main directory to have it pick files from all its subdirectories.

RandomSlide uses its own viewer to display the images, and they are shown in full-screen mode by default. The program also allows you to open an image’s source folder when it is on the screen.

Once you have selected a folder, you can set the preferred delay, which can be anywhere from 1 to 60 seconds. However, there is no option to switch between images manually.

Images are selected at random, which most users should be happy with. No alternatives are available, however, such as sorting files by name or by date.

You can select which of the available monitors the slideshow should be displayed on, and the program is even capable of setting the images as your desktop background. Unfortunately, though, you can’t specify how they should be fit to your screen.

On the whole, RandomSlide isn’t a particularly impressive application, but it does its job well enough. It is easy to set up and doesn’t even require installation, but it would be great if more customization options were added in future releases.
