string sql="SELECT * FROM nImage WHERE ID = '" + Request.QueryString["ID"] + "'";

string xPath="D:"+ System.IO.Path.DirectorySeparatorChar + "HomePage" + System.IO.Path.DirectorySeparatorChar+ "WebGKM2"+ System.IO.Path.DirectorySeparatorChar+"bin"+ System.IO.Path.DirectorySeparatorChar+ "WebImage.mdb";
string ConStr="Provider=Microsoft.Jet.OLEDB.4.0; Data Source="+xPath;
OleDbConnection connection = new OleDbConnection(ConStr);
OleDbCommand command = new OleDbCommand(sql, connection);
connection.Open();
OleDbDataReader dr = command.ExecuteReader();
if(dr.Read())
{
Response.Clear();
Response.AddHeader("Content-Type",(string)dr["nType"]);
Response.BinaryWrite((byte[])dr["nImage"]);
}
Response.End();
dr.Close();
connection.Close();
connection.Dispose();
