  Firstly, identify if the problem is with a jpeg or bitmap...
  
  try loading a bitmap in - if you don't get an AV, you need to ensure you have the JPEG define in fr.inc (also include the jpeg unit in your uses clause).
  
  you could also try creating a TJPEGFile, using LoadFromFile with this and then PV.picture.assign(ojpegfile).

  still the same AV in that same place
  even when i want to load bmp is the same - but i have to load jpg
  but i would be grateful if i could load bmp than i try to load jpg
  check this code - probably there is something wrong?? i dont know because it's look like it was problem with PV object.. i realy don't know

  i have found solution
  
  i add script to Picture1 (TfrPictureView object) :
  
  begin
  Picture1.LoadFromFile(filename)
  end
  
  and it doesn't matter if it is bmp or jpg
  
  but i would like to know how to do it in delphi

  modify your code a little
  from this
  var PV: TfrPictureView;
  begin
  guzial_ini := TINIFile.Create('../plik2.ini');
  frReport4.LoadFromFile('test4.frf');
  PV := TfrPictureView.Create;
  PV :=(frReport1.FindObject('Picture1') as TfrPictureView);
  PV.Picture.LoadFromFile('c:\a.jpg'); <- exeption there is something wrong
  frReport4.PrepareReport;
  frReport4.ShowReport;
  end;
  to this
  var V: TfrView;
  begin
  guzial_ini := TINIFile.Create('../plik2.ini');
  frReport4.LoadFromFile('test4.frf');
  V :=(frReport1.FindObject('Picture1');
  tfrpictureview(V).Picture.LoadFromFile('c:\a.jpg');
  frReport4.PrepareReport;// don't need if calling showreport or if you call prepare then use showpreparedreport instead of ShowReport;
  end;
  tip
  turn on auto code completion and when writing code like this
  tfrpictureview(V).Picture.LoadFromFile('c:\a.jpg');
  when you type the period wait and you will find all the classes properties and their types available to you at that point.
