How to Change a Windows 8 Wallpaper (Still or Slideshow)

Slideshow Wallpaper

1. 
   Find the wallpaper you want. You can try looking for good ones in Google images or other image websites.
2. 
   Save your wallpaper as an image to your computer. This can be done by right-clicking on the image and clicking "Save image as..." Then select the location you want it to be saved to, give it a title and press "Save".
3. 
   Go to your desktop. If you're on the Start screen, click on the search button in the top right corner of your screen, and type "Desktop". Click on the purple icon with the white rectangles; it will likely be the first one on the list.
4. 
   Right click on your desktop (away from any icons) and press "Personalize". 
5. 
   On the bottom of the menu that just popped up, click "Desktop Background".
6. 
   Click "Browse", somewhat towards the top of the menu. Windows Explorer should open up.
7. 
   Search through the list for the folder/location you saved the images to. When you've found the folder you want, click on it and press "Ok".
8. 
   Hold down the Control (Ctrl) key and click on your wallpapers. A checkbox should appear beside each one. If you want the images to shuffle, meaning flip in a random order, check the box titled "Shuffle" (recommended).
9. 
   Set the amount of time you want each image to stay on screen before transitioning. Now all that's is to click save changes.
