If you know how to change your Chromebook's wallpaper and themes, you can customize the desktop and Google Chrome. You can even choose one of your images for the Chromebook background.
Instructions in this article apply to laptops with Chrome OS, regardless of who made the device.
Chromebook Themes and Wallpapers
Chromebooks are lightweight laptops made primarily for productivity applications and browsing the web. In addition to several pre-installed wallpapers, the Chrome Web Store has tons of free themes that alter the appearance of the Google browser. While many models are available, the Chrome OS interface is standard across all devices, so the steps for changing the wallpaper and theme is the same for all Chromebooks.
You don't need a Chromebook to customize the Google Chrome theme. You can also create Chrome themes.
