I don't know about these 2 statements but I can add that: Pixels won't return garbage when you read them from very big images IF the portion that you read is on screen (fitting in screen resolution).
That's a statement from previous experience with (loaded)images of 4000*600 or bigger (don't know if there is a limit) and this on all my computers (got 4, all different videocards and cpu). I was scrolling the image and saving bmp's of 800*600.
