一个自动动态播放图片的类（downmoon）新增图片效果

第一步：创建一个类clsTurnPicture

增加方法如下　：

/// <summary>

/// 播放图片类(downmoon)

/// </summary>

/// <param name="arrImgName">arrImgName</param>

/// <param name="arrDesc">arrDesc</param>

/// <param name="strShopName">strShopName</param>

/// <param name="strBrandName">strBrandName</param>

/// <param name="strResoourceCode">strResoourceCode</param>

/// <param name="ScrWidth">ScrWidth</param>

/// <param name="ScrHeight">ScrHeight</param>

/// <param name="PicWidth">PicWidth</param>

/// <param name="PicHeight">PicHeight</param>

/// <param name="TextHeight">TextHeight</param>

/// <param name="ToolBarHeight">ToolBarHeight</param>

/// <param name="FontSize">默认为16,px</param>

/// <returns></returns>
