this photo was from one of the last episodes of Star Trek Next Generation, directed by Patrick Stewart.
this was one of the Deep Space Nine episodes (one of the two as an ore miner) .
From Voyager: these are a few shots of the Krenim officer (at the time I didn't know that name, I called it Lizard boy due the iguana pearls)
also from Voyager a villager, not sure of the episode.
and this final shot also from Voyager as a space prisoner.
