if you haven't got a program that can edit dds files then download
thegimp
then a dds plug-in
also might want to download a dds thumbnail viewer
google for them
then look into your
\Conquer 2.0\c3\effect
folder, you can edit your pictures there, alot will be missing they seem to do sometihng so you cant see them, someone explained it in a old post and cba to type it out again
