The user interface is simple and straightforward; drag any image into the box on the right, and it will replace the current background image of your Hackintosh's login screen. You can reset it back to the default image at any time.
I personally recommend replacing the login screen background with your desktop wallpaper. You can find the default wallpapers for Mac OS X in /Library/Desktop Pictures . Of course, the choice is completely up to you.
Alternatively, instead of using Loginox, you could replace the login screen of your Hackintosh manually. This process requires a lot more involvement (and some basic image editing skills), but it's great for anybody who would rather do it themselves.
