In the episode teaser, whenever The Doctor takes a picture of the crew members, the diaphragm effect is actually a mosaic of Ensign Jetal's face.
The Doctor's imaging device was fashioned from a radio control transmitter.
Freeze framing during the first scene where the holographic pictures are being taken, the pictures that are making up the "shutter" are still images of Ensign Kim and Ensign Jetal.
The Doctor's lines "Are you making fun of me?" and "You're conspiring against me!" and Captain Janeway's line "I've got a mutiny on my hands" were all later reused during the holomatch section of the video game Star Trek Voyager: Elite Force (2000).
