Simple JQuery gallery using the FB API.

README

You need to add in the dependancies for fancybox http://fancybox.net/
And ensure that JQuery is included to the module, 

Facebook part
You need an appID which you  can register for via developer.facebook.com
You can use what's called a channel which allows for a caching some scripts. 
You need to find the pageID of the page you are calling

You can set all of these are the start of the script. 

Any questions drop me an email

gallery.js

window.fbAsyncInit = function() {
  
  var appID = "";
  var channelURL = "";
  var pageID = "";
  
  // init the FB JS SDK
  FB.init({
    appId: appID, // App ID from the App Dashboard
    channelUrl: channelURL, // Need to sort this out.
    status: true, // check the login status upon init?
    cookie: true, // set sessions cookies to allow your server to access the session?
    xfbml: true // parse XFBML tags on this page?
  });

  if (typeof facebookInit == 'function') {
    facebookInit();
  }

};

// Load the SDK's source Asynchronously
// Note that the debug version is being actively developed and might 
// contain some type checks that are overly strict. 
// Please report such bugs using the bugs tool.
