  Use this toggle to turn background images on/off. When off, a blank gradient background will be shown with now images.
• Customize backgrounds
  If you have the Show Background Image toggled "on", you can use the four boxes to select what specific types of images you want to display on the New Tab Page:
  
  • Use your own — Allows you to upload your own images from your desktop to display on the New Tab Page.
  • Brave backgrounds — Selecting this option will display one of Brave's many hand-picked images (many submitted by users) that come pre-packaged with the browser.
  • Solid colors — This option will display a single solid color on the New Tab Page. Note that you can pick one color you like and have that display on every new tab, or you can toggle the Refresh on every new tab option "on" to display a different color at random each time you open a new tab.
  • Gradients — Similar to the Solid colors option, this will allow you to change the New Tab Page background to a gradient color pattern.
• Show Sponsored Images
  Sponsored images will appear on every fourth new tab opened. You can opt-out of seeing these sponsored images by toggling this option off. Note that sponsored images will still appear regardless of which background image option you've chosen as long as it's toggled "on".
