I'm currently working on improving the pyStation in our forked repo.
You can take a look at the upload_image.py script.
https://github.com/Chaostreff-Potsdam/zonen-tags/blob/docker/tag_configurator/upload_image.py

For the original PyStation you need to put your images in a sub-directory named cache.
Also make sure that your current working directory is ARM_Tag_FW/cc2531_OEPL/OpenEPaperLink-PyStation and running the main.py as a script from there like python3 main.py.
