  Use the following code, but all the photo shown are same!
  

  procedure TForm1.Button1Click(Sender: TObject);
  begin
    PV:=(frReport1.FindObject('Picture1') as TfrPictureView);
    frReport1.ShowReport;
  end;
  
  procedure TForm1.LoadPhoto;
  var
    S,FileName:String;
  begin
    S:= trim(ADOTable1.FieldByName('EmpID').AsString);
    {The FileName of the photo actual the ID of employee!}
    FileName:='C:\Documents and Settings\Administrator\My Documents\My Pictures\'
          + S +'.bmp';
    if FileExists(FileName) then
    begin
      PV.Picture.LoadFromFile(FileName);
    end;
  end;
  
  procedure TForm1.frReport1Progress(n: Integer);
  begin
    LoadPhoto;
  end;

  The question are RESOLVED.
  But my English is so pool, so I doesn't translate it to English, Sorry!

  问题我自己解决了，道理很简单：
  主要是要在适当的时候载入照片。我原来是在报表的OnProgress事件中载入照片的，但这时的报表还算是模板，故预览时就会被固定为一个照片。现在把载入照片的代码放到报表的OnBefore事件中执行，显示结果就正确了，因为这时报表已经不是模板，而是预览后的报表！
  完整的代码如下：
  
  unit Unit1;
  
  interface
  
  uses
    Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
    Dialogs, StdCtrls, FR_Class, jpeg, ExtCtrls, DBCtrls, DB, FR_DSet,
    FR_DBSet, ADODB;
  
  type
    TForm1 = class(TForm)
      Image1: TImage;
      frReport1: TfrReport;
      Button1: TButton;
      ADOConnection1: TADOConnection;
      ADOTable1: TADOTable;
      DataSource1: TDataSource;
      frDBDataSet1: TfrDBDataSet;
      ADOTable1EmpNo: TStringField;
      ADOTable1EmpName: TStringField;
      ADOTable1Photo: TBlobField;
      procedure Button1Click(Sender: TObject);
      procedure frReport1BeforePrint(Memo: TStringList; View: TfrView);
    private
      { Private declarations }
      PV:TfrPictureView;
      procedure LoadPhoto;
    public
      { Public declarations }
    end;
  
  var
    Form1: TForm1;
  
  implementation
  
  {$R *.dfm}
  
  procedure TForm1.Button1Click(Sender: TObject);
  begin
    PV:=(frReport1.FindObject('Picture1') as TfrPictureView);
    frReport1.ShowReport;
  end;
  
  procedure TForm1.LoadPhoto;
  var
    S,FileName:String;
  begin
    S:= trim(ADOTable1.FieldByName('EmpNo').AsString);
    FileName:='C:\Documents and Settings\Administrator\My Documents\My Pictures\'
          + S +'.jpg';
    if FileExists(FileName) then
    begin
      PV.Picture.LoadFromFile(FileName);
    end;
  end;
  
  procedure TForm1.frReport1BeforePrint(Memo: TStringList; View: TfrView);
  begin
    LoadPhoto;
  end;
  
  end.
