Hi Thomas,
I think you're learning lots and your coding style has improved remarkably.
Well done.

I suspect the problem is that you display first then move to the next
position. The usual way to render moving images is ...

  if image was displayed then
     hide it at its current position
  end if
  move to the new position
  display the image

I'm not expert here so maybe somebody else can elaborate.
