导出到Excel，不导出图片，那位大侠能解决。
代码如下：我的Repeater中是有图片的。请问，我导出的时候，怎么把图片给排除掉。

        public static void ToExcel(System.Web.UI.Control ctl, string FileName)

        {

            HttpContext.Current.Response.AppendHeader("Content-Disposition", "attachment;filename=" + FileName + ".xls");

            HttpContext.Current.Response.Charset = "UTF-8";

            HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.Default;

            HttpContext.Current.Response.ContentType = "application/ms-excel";//image/JPEG;text/HTML;image/GIF;vnd.ms-excel/msword 

            ctl.Page.EnableViewState = false;

            System.IO.StringWriter tw = new System.IO.StringWriter();

            System.Web.UI.HtmlTextWriter hw = new System.Web.UI.HtmlTextWriter(tw);

            ctl.RenderControl(hw);

            HttpContext.Current.Response.Write(tw.ToString());

            HttpContext.Current.Response.End();

        }
