how to install KDE 4 to lenny from iso disc image?
Assuming you mean the demo KDE 4 live cd you can't. KDE 4 is in experimental, there's some doc on http://pkg-kde.alioth.debian.org/experimental.html which explains how to install it on a lenny/unstable system.
I compiled my KDE 4 from the SVN sources and TBQH it's still quite unstable. YMMV.
