Clowp

If you own several computers, be they laptops, notebooks or desktop PCs, you probably have a different desktop wallpaper on each of them, since selecting the same one on all of them can be a time-consuming task. However, you can rely on Clowp to simplify this job and enjoy the same selection of wallpapers on all your devices.
First of all, you need to make sure you have .NET Framework 4.5 installed on your computer, otherwise you first need to install it, then get to use the functions of Clowp.
Next, you need to create an online account that would help you gain access to the same desktop background images - you simply need to use the same credentials on all your devices, then choose the wallpapers you prefer.
You can add your favorite graphic files, then upload them to an existing public album or create a dedicated gallery, if you want your pics to remain private. You can also assign them to a playlist, so that you can select it when needed.
Furthermore, you can switch to a new wallpaper with a single mouse click, by accessing the functions of Clowp via its system tray icon. You can specify if you are interested in viewing only the images you uploaded yourself, or if you want to get all the Clowp wallpapers on your desktop.
Additionally, if you want to modify the rotation interval, you need to login with your credentials on the website and enter the frequency you prefer, in minutes.
All in all, Clowp can help you enjoy your chosen wallpapers on all computers where the same credentials are used - you can set it to run at startup and you will no longer need to manually choose a new desktop background when you are bored with the current one.
