string strQuery = "select Name, Data from tblFiles where userid=@id";
        SqlCommand cmd = new SqlCommand(strQuery);
        cmd.Parameters.Add("@id", SqlDbType.Int).Value
        = Convert.ToInt32 (5248);
        DataTable dt = GetData(cmd);
if (dt != null)
        {
	if(dt.Rows[0]["Data"] !=DBNull.Value)
	{
	byte[] bytes = (byte[])dt.Rows[0]["Data"];
        string base64String = Convert.ToBase64String(bytes, 0, bytes.Length);
        Image1.ImageUrl = "data:image/png;base64," + base64String;	
}
if(dt.Rows[1]["Data"] !=DBNull.Value)
	{
	byte[] bytes = (byte[])dt.Rows[2]["Data"];
        string base64String = Convert.ToBase64String(bytes, 0, bytes.Length);
        Image2.ImageUrl = "data:image/png;base64," + base64String;	
}
if(dt.Rows[2]["Data"] !=DBNull.Value)
	{
	byte[] bytes = (byte[])dt.Rows[2]["Data"];
        string base64String = Convert.ToBase64String(bytes, 0, bytes.Length);
        Image3.ImageUrl = "data:image/png;base64," + base64String;	
}
if(dt.Rows[3]["Data"] !=DBNull.Value)
	{
	byte[] bytes = (byte[])dt.Rows[3]["Data"];
        string base64String = Convert.ToBase64String(bytes, 0, bytes.Length);
        Image4.ImageUrl = "data:image/png;base64," + base64String;	
}
