So, I've tested your scene: once how you pasted
it here, and once with commenting the first, pure
no_image sphere in (and the latter one, with the
"normal" sphere inside, was commented out, of
course).

On both cases, it doesn't detect the no_image object,
but only the inner sphere with .5 radius.

I've got the official POV-Ray 3.5, Windows 2000,
768 MB DDR-RAM on AthlonXP 2400+.

Aside of that though:
IF the trace is based on the tracing rays of the
viewing screen, then I'd GUESS that it actually never
would  hit a no_image object anyway. Much like
radiosity doesn't see no_image objects. But
thats just a WILD GUESS which any newbie without
background knowledge should NOT listen to.

Rune, can you post a small example where it does
hit a no_image object?
