","" ); Response.BinaryWrite(ThumbData); Response.Flush(); Response.End(); } else { foreach ( string thumb in ThumbLib.GetThumbfiles()) { if (System.IO.File.Exists(Server.MapPath( " . " ) + " // " + thumb)) { // Could use a Literal control here if you want more // control over the html. System.Web.UI.WebControls.Image ThumbImage = new System.Web.UI.WebControls.Image(); ThumbImage.ImageUrl = " thumbs.aspx?thumb= " + Server.UrlEncode(thumb); ThumbImage.ImageAlign = ImageAlign.Top; ThumbImage.AlternateText = thumb; ThumbImage.BorderStyle = BorderStyle.Outset; ThumbImage.BorderWidth = new Unit( 1 ); ThumbImage.Attributes.Add( " hspace "," 4 " ); ThumbImage.Attributes.Add( " vspace "," 4 " ); ThumbImage.Attributes.Add( " onclick "," window.location.href=' " + thumb + " '; " ); ThumbImage.Style.Add( " cursor "," hand " ); plcThumbs.Controls.Add(ThumbImage); } } } ThumbLib = null ; } else { Response.Write( " Thumbs.db Not Found!
