    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.
