1. Add the Static FBML App
The tabs at the top of your Facebook Fan Page are apps. Some, like your wall and photos are built into Facebook. Others are essentially plug-ins where fans can view external content, like YouTube videos, Flickr photos, etc.
The app you need for your custom page is called “Static FBML,” located here. If you’re logged into Facebook, you can add it to your Page. It is essentially a blank canvas where you can add whatever content you want, including custom graphics and links via standard HTML.
