I like to change my wallpaper everyday because every new picture on my desktop makes my day more thrilling and adventourous. It also refreshes my mood from time to time and I can assure it's some kind of psychological feature that also enhances productivity.
Changing your wallpapers manually everyday is time taking and boring, instead we can automate the change with some tools and tricks already available for free.
Well, there are many tools out there but these are the ones that I have used and tested for long enough to include in the following list.
Splash! - Unsplash Wallpaper
This is an app for windows available through the windows app store and a good enough choice for automatically changing the wallpapers on the lockscreen or the desktop, the wallpapers are pulled from the unsplash and it is pretty easy to setup but is only available for users of Windows 10.
Bing Desktop is another application program that can automate your wallpapers everyday, it primarily pulls the wallpaper from the Bing Gallery everyday but it also has other sources for images with section like animals, other, trending etc.
The program is pretty simple and also includes the search facility for direct results from the Bing search engine.
Dynamic Theme is a wonerful app totally awesome and feels like the native windows personalization app, with advanced features like wallpaper synchronization over networked computers.
It offers wide range of choices for wallpapers from Bing, Windows Spotlight, Photo and Slideshow. This app is good enough with great wallpapers. I really liked the native look it offers, similar to windows own's personalization app.
SpotBright, is another nice app for wallpapers everyday, the app has free version with limited features and offers pro version for features like automatically setting new wallpapers though you can download any number of images at once.
The best thing about this app which is available through the windows store is that the images it offers are awesome, and are very high in quality and pleasure.
So I hope you try these apps and check what each has to offer in great detail. I am currently using SpotBright images with windows native slideshow feature.
