When it comes to automatically change wallpapers after certain time intervals, most users are extremely satisfied with the features of Windows 7/10 itself and do not really see the need to install additional tools.
John's Background Switcher, however, is a tool that does this, but much more than that. To change the background, it can "drag" photos from your hard drive, but also from photo sharing sites, such as Flick, SmugMug, Unsplash, and Instagram.
John's Background Switcher, or JBS, does not discriminate in terms of the number of displayed images and can display editing from several images on the screen, as well as arranging them in a visually-executable mosaic.
The latest, fifth version allows you to view photos from Google Photos as well as to view photos from absolutely all supported sources, or photo sharing sites. We also like the fact that the latest version is no longer bothering and correctly displaying high-resolution screenshots.
The free application is available for Windows or Mac.
