Just Install the plugin, then you can see the login form has changed, 
after this go to the Settings->custom-login & put your logo & background image link which you want. 
Enjoy.

NOTE: in Custom Login 4.4, PHP 8.1 or greater was required, but in version 5.x, PHP requirements were 
dropped back to 7.4 or greater. Enjoy the update.
Custom Login 3.0 was 200% faster than version 2.0, and version 4.0 and 5.0 is now even better!
