Microsoft MFC imagelist

How to add more images in ImageList? How to display them in different places using the coordinates or something else? How to display pictures of a larger size (48 - the maximum size of the displayed image, they simply are not larger)

Code from the site

I do not even know how they got an example with the image of 800x800

CMFCImageListDemoView::CMFCImageListDemoView(){ 
  ImageList.Create(48, 48, ILC_COLOR, 4, 1);

  CBitmap bmp;
  bmp.LoadBitmap(IDB_BITMAP1); 
  ImageList.Add(&bmp, RGB(0, 0, 0));
}
