Why does Ubuntu CD contain a "pics" folder with Debian-related images?
These documents become part of the debian-cd plan, which is made use of to construct the Ubuntu real-time CDs.
The photos are sourced by an include documents called
README.html.in, which the
add-bin-doc device includes right into
README.html at the origin of the CD is filesystem. This documents is either never ever created or is removed from Ubuntu is CDs, so I think the photos are extra.
