> Does anyone have pics of Zacks butt in Desire?

Nope. Didn't cap it.

> and if you buy the DVD Set of Ray bradbury do they show the episode of
> Zack in the Black ferris?

I don't own it; but I checked Amazon. It's on the "Complete Series"
collection (not sure which disc it'd be on; it's a 5-disc set), and
probably one of the other smaller volumes.

> has Zach done any other nude scenes?

Shirtless, yes (see 'The Secret Path', aka 'Chasing Secrets'; and
'Looking for Miracles' when he was younger). But aside from 'desire',
no nude scenes I know of.
