How to get user's profile picture with Facebook's Unity SDK?

Question

I'm trying to get the profile pic of the user of the game using this-

void MyPictureCallback(FBResult result) // store user profile pic
{
        if (FB.IsLoggedIn)
        {
            WWW url = new WWW("http" + "://graph.facebook.com/" + FB.UserId + "/picture");

            Texture2D textFb2 = new Texture2D(128, 128, TextureFormat.ARGB32, false); //TextureFormat must be DXT5

            url.LoadImageIntoTexture(textFb2);
            profilePic.renderer.material.mainTexture = textFb2;
        }

But it isn't working. I am getting no errors.

Jason Pietka's answer is OK but a bit old. Today we us FB.API:

FB.API("me/picture?type=med", Facebook.HttpMethod.GET, GetPicture);

GetPicture is a callback method so:

private void GetPicture(FBResult result)
{
    if (result.Error == null)
    {          
        Image img = UIFBProfilePic.GetComponent<Image>();
        img.sprite = Sprite.Create(result.Texture, new Rect(0,0, 128, 128), new Vector2());         
    }

}
