fade in out multi images then go to next scene

Hello, Im just new in Unity 3D, I having a problem: I want to fade in fade out some logo (as a start game usual). I found out this script very useful: http://www.unifycommunity.com/wiki/index.php?title=FadeInOut When i try apply the 2nd image, it just appear at the same time with 1st image And after load logo, the scene doesnt go to scene 2 as i want. this is my code:

 // FadeInOut

// //-------------------------------------------------------------------- // Public parameters //--------------------------------------------------------------------

public var fadeOutTexture : Texture2D;

public var fadeOutTexture2 : Texture2D;

public var fadeSpeed = 0.1;

var drawDepth = -1000;

var drawDepth1 = -1000;

//-------------------------------------------------------------------- // Private variables //--------------------------------------------------------------------

private var alpha = 1.0;

private var fadeDir = -1;

private var alpha1 = 1.0;

private var fadeDir1 = -1; //-------------------------------------------------------------------- // Runtime functions //--------------------------------------------------------------------

//--------------------------------------------------------------------

function OnGUI(){

 alpha += fadeDir * fadeSpeed * Time.deltaTime;  
 
 alpha = Mathf.Clamp01(alpha);   
 
 alpha1 += fadeDir1 * fadeSpeed * Time.deltaTime;  
 
 alpha1 = Mathf.Clamp01(alpha1);   
 
 GUI.color.a = alpha;
 
 GUI.depth = drawDepth;
 
 GUI.color.a = alpha1;
 
 GUI.depth = drawDepth1;
 
 GUI.DrawTexture(Rect(550, 250, 200, 83), fadeOutTexture);
 
 GUI.DrawTexture(Rect(550, 250, 200, 200), fadeOutTexture2);

 

}

//--------------------------------------------------------------------

function fadeIn(){

 fadeDir = -1; 
 
 fadeDir1 = -2; 
 

}

//--------------------------------------------------------------------

function fadeOut(){

 fadeDir = 1; 
 
 fadeDir1 = -2;     

}

function Start(){

 alpha=1;

fadeIn(); alpha1=2;

 fadeIn();
 
 Application.LoadLevel(2);

}
