Change Chrome New Tab Background Picture With The Theme

[kkkkostia]

This script changes Chrome's new tab background picture with the theme, since even though Chrome supports having custom picture as a new tab background, the picture will stay the same regardless of the theme.

The script works by switching a file used by Chrome to display user's new tab background - background.jpg file, that Chrome creates in its folder by copying your custom picture when you upload it as a background

1. Create Set-ChromeBg folder with the following file structure:

Use its path later in place of <...> in scripts.yaml and Set-ChromeBg.ps1

Set-ChromeBg
├───dark.jpg #your picture for dark mode
├───light.jpg #your picture for light mode
└───Set-ChromeBg.ps1

2. Set-ChromeBg.ps1 :

function Set-ChromeBg ([string]$theme){
	cd 'C:\<...>\Set-ChromeBg'
	
	if ($theme -eq 'light') {
		cp light.jpg 'C:\Users\<username>\AppData\Local\Google\Chrome\User Data\Default\background.jpg'
	}
	
	if ($theme -eq 'dark') {
		cp dark.jpg 'C:\Users\<username>\AppData\Local\Google\Chrome\User Data\Default\background.jpg'
	}
}

3. Inside of scripts.yaml :

Enabled: true
Component:
  Scripts:
  - Name: Change Chrome New Tab Picture
    Command: pwsh
    ArgsLight: [-command, ". C:\\<...>\\Set-ChromeBg\\Set-ChromeBg.ps1; set-chromebg -theme 'light'"]
    ArgsDark: [-command, ". C:\\<...>\\Set-ChromeBg\\Set-ChromeBg.ps1; set-chromebg -theme 'dark'"]
    AllowedSources: [Any]

4. After changing the theme, reload the home page or open a new one to see the changes.

Warning

If you currently don't have any custom picture set as your new tab background, you need to do it first (Customize Chrome > Change Theme > Upload Picture) for script to work.

I guess it has to do with the setting "custom_background_local_to_device":false in Chrome's Preferences file
