Doom RAW image viewer

I've been mucking around with the doom picture format for a couple of
years now, since I have found it soooo damn hard to understand and
translate the UDS (bah)

anyway, the result of 2 days work (and some 'borrowed' code here and
there) has pretty much given me this:
http://russell.slipgate.org/files/DViewer.zip

it includes Delphi source and a precompiled binary.

I have no idea why I created this 'program', I had to find something
to do on my 19th birthday :P
