How to load a JPEG image from resource file?

Is the resource a custom resource? i.e JPEG internal,
or is the resource just a standard BMP?

It's a custom resource(I import it with J++).

This is from Borland groups. Hope this helps:

                  Make a resource file like so:

                  <---- Cut ---->

                  SPLASHBACKGROUND JPEG "..\Images\Splash\Splash.jpg"

                  <---- Cut ---->

                  Save that as images.rc (or whatever)

                  Run brcc32 images.rc (in your Program Files\Borland\Delphi 3\Bin folder)

                  This will make images.res

                  Add the resource to a DLL or your main project like so:

                  {$R Images.Res}


                  Then use this function... If you are not using a DLL just pass in
                  Application.Handle
                  Pass in SPLASHBACKGROUND and then pass in Image1.Picture.

                  Procedure LoadJPEGFromRes(TheDLLHandle : LongInt; TheJPEG : String;
                  ThePicture : TPicture);
                  Var TmpResHandle : THandle;
                      TmpMemHandle : THandle;
                      TmpMemStream : TMemoryStream;
                      TmpResPtr : PByte;
                      TmpResSize : Longint;
                      TmpJPEGImage : TJPEGImage;
                  Begin
                   TmpResHandle := FindResource(TheDLLHandle, PChar(TheJPEG), 'JPEG');
                   TmpMemHandle := LoadResource(TheDLLHandle, TmpResHandle);
                   TmpResPtr := LockResource(TmpMemHandle);
                   TmpMemStream := TMemoryStream.Create;
                   TmpJPEGImage := TJPEGImage.Create;
                    Try
                     TmpResSize := SizeOfResource(TheDLLHandle, TmpResHandle);
                      TmpMemStream.SetSize(TmpResSize);
                      TmpMemStream.Write(TmpResPtr^, TmpResSize);
                      FreeResource(TmpMemHandle);
                      TmpMemStream.Seek(0, 0);
                      TmpJPEGImage.LoadFromStream(TmpMemStream);
                      ThePicture.Assign(TmpJPEGImage);
                    Finally
                     TmpJPEGImage.Free;
                     TmpMemStream.Free;
                    End;
                  End;
