	参数直接赋值法
	new FlashPicture(ID,Width,Height,AutoTime,Tween,ShowButton,TitlePosition,LinkMode,TitleColor,TitleBackground,TitleAlpha,ButtonColor,ButtonOver)

	参数动态赋值法
	var FlashNews = new FlashPicture(ID)	*此参数必选
	FlashNews.Width = 400;
	FlashNews.Height = 300;
	FlashNews.AutoTime = 5;
	FlashNews.Tween = 0;
	FlashNews.ShowButton = 1;

	FlashNews.TitleAlpha = 60;
	FlashNews.ButtonColor = "888888";
	FlashNews.ButtonOver = "999999";
	FlashNews.Show();

	参数说明:
		ID					"ObjectID"					容器ID					(必选)
		Width				(400)
		Height				(300)
		AutoTime			(3)						自动播放时间：单位是秒
		Tween				(2)						图片过渡效果：0，表示亮度过渡，1表示透明度过渡，2表示模糊过渡，3表示运动模糊过渡
		ShowButton			(1)						是否显示按钮：1表示显示按键，0表示隐藏按键，更适合做广告挑轮换
