Install
This is the repository archive. It installs, but the folder name will carry the branch suffix and updates will not flow.
Install straight from GitHub with WP-CLI:
wp plugin install https://github.com/constracti/wp-login-image/archive/refs/heads/master.zipNo built-in updater. New versions won't appear under Dashboard → Updates. Install new releases yourself, or let Git Updater track the repository.
The login screen image is a link to your blog's Home, with the blog's Name as a title. Background is a randomly selected from your Media Library file which has its title set to 'kgr-login-image'.
