Merging .img files into a single PDF

Prerquisites:

imagemagick should do the trick. Install it on macOS:

brew install imagemagick

Step by step

1. Get the images in one folder
2. Open that folder in Terminal
3. Run convert *.jpg title.pdf

If page numbers encoded in filenames aren’t in order, run this command instead:

convert $(ls -1 outline-functional-model-nervous-system-*.jpg | sort -t'-' -k6 -n) title.pdf

It will produc a title.pdf file in that same directory.

convert $(ls -1 MODEL_OF_THE_NERVOUS_SYSTEM-page*.jpg | sort -V) MODEL_OF_THE_NERVOUS_SYSTEM.pdf

The -V flag does "version sort" which handles numbers correctly (1, 2, 3... 10, 11 instead of 1, 10, 11, 2, 3).
