To create the above gif, I made 5 batches each consisting of 19 layers. (1 white backgrounds, 2 main subjects, 3 princess, 4 text and 5 star)
Each block was saved as a .xcf file (uploaded in the following two posts)
Then > File > Open as Layers (all 5 batches), this opens 95 layers
Run this script

located at <Image>/Layer/Stack/Assemble for gif
on this image with a value of 5, the result can be played or saved
This is a roundabout way of creating gifs, but allows quick reruns using some or all or adding new batches with little effort
