How do you think I took over the world?
FQM isn't an old mod though. There were some other mods that I found with planet pics in them in the old Shrapnel downloads section, which I got the planets from and submitted to the Image Mod. I forget what they were named though.
I am not sure if the Krsqk System mod or Deathstalker's Quad Mod (some more recent mods) had planet pics in them or not. D's mod is on the Gold CD, and I am sure you could find Krsqk's mod with a quick search. I think Daynarr made some sort of planet/quadrant mod at some point too.
