The first step to getting your custom log-in page up and running is to download a plug-in. There are other ways that you can go about editing the default page through html and css, however using a plug-in is the simplest and most beneficial way to go about it. This way you can be sure that you are keeping good clean code in your website, and the design of the page will be much easier to work with. The plugin you are going to want to download can be found here. For future reference, if this link was to have ever been broken, you can always search Google for the plugin which is called "bm-custom-login." After you have downloaded the plug-in, you are going to want to open the folder and navigate to the image>login-bkg-tile-sample. Open this file with Photoshop, or a similar image editor. After you have done that, you are ready to customize.
