. It's just copy/paste, and then tweak the layers?
Yup. Just that simple. IIRC, they aren't transparent GIF's, so you will need to clip the edges if you want clean overlaps with the layers.
The Pamela Anderson reminded me of the big-boobed spaceship (piloted by John-Boy Walton) in Battle Beyond the Stars.
Wow...there's a blast from the past. To show my age, I remember when that movie first aired. I was very young, but it still seemed very creepy to me in comparison to Wars or Trek. The transplanted arm scene with the telepathic aliens, to me, was the defining moment in that movie. Never saw anything quite like that before or since.
