The best way is to google for "star trek panels". Most of the pics wont show them from a frontal angle, but you can always use photoshop to correct the perspective. There was an old HLDM star trek map that came with a WAD file, so I think the author wouldnt mind if you used it. I would have let you used my wad file if you hadnt posted such a stupid comment when reviewing my map "Warpcore".
"I will chase you around the moons of Nebir and around Paritions flames" if you decompile my maps...

Seriously, it isnt so hard to make your own textures. Noone knows as good as you what textures you need to make the map.
