If there is no no 'images' folder in this directory, then these have not 
been included in the published release archive to minimize its file size. 

Please find the images at:

https://codeberg.org/coalispr/coalispr/src/branch/main/docs/_static/images


To get the images in place:

0. Open a terminal in the source folder with this file.
1. Download the images as tar.gz or zip archive.
2. Unpack the archive and 
   Rename the created folder ('coalispr') to 'images'.

Thus, from a terminal in the extracted source folder with this file, run:

1.  wget https://codeberg.org/coalispr/coalispr/archive/main:docs/_static/images.zip
2a. unzip images.zip
2b. mv coalispr images

or

1.  wget https://codeberg.org/coalispr/coalispr/archive/main:docs/_static/images.tar.gz
2.  tar -xvzf images.tar.gz --transform 's/coalispr/images/'
