Problem with LXDE images with Debian. Are prepared for run without network?

[Pedro <pederindi@gmail.com>]

Hi,

(I try some conversation in IRC, but nobody answers)

I tried:
debian-7.1.0-i386-lxde-CD-1.iso
debian-live-7.0.0-i386-lxde-desktop.iso

expecting to install Debian LXDE without Internet. I can't. It is demanding apt sources, and if I ignore, installation fail.

Suggestions?
Thanks

Pedro
