This knowledgebase article will show you how to customize the LoginPress default Theme Background image with a hook while using Multisite Network.

Customizing LoginPress Default Theme Background Image while using Multisite Network

If you want all the sites on your Multisite network to use the other than LoginPress default Theme Background image on the login page, add a hook in your main website theme's functions.php file.

Note: It’s recommended to use a child theme to edit the functions.php file instead of the parent theme. There are chances to lose the modified code when you update your theme. It might cause some adverse effects on your website.

Here is the hook:

function loginpress_default_bg_callback( $background ) {
  $background = 'https://cdn.pixabay.com/photo/2019/07/19/09/40/flowered-balloon-flower-
4348351_960_720.jpg';
  return $background;
}
add_filter( 'loginpress_default_bg', 'loginpress_default_bg_callback' );

Note: Here, $background contains the URL for the background image. You can change the image to any image of your choice simply by replacing the URL. Ensure the image is optimized. Otherwise, it can cause the login page to load slowly.

Once you’ve added the hook in the main website theme's functions.php file, the default LoginPress themes background will look like this:
