Photogallery for Inky Impression color e-ink display connected to Raspberry Pi.

See my blog on building a DIY Color E-Ink Picture Frame for additional details.

• Connect the Inky Impression e-ink display to the Raspberry Pi (I am using a Raspberry Pi Zero W)
• Install the Raspberry Pi operating system on the Pi
• Enable I2C and SPI using sudo raspi-config for the Raspberry Pi to interact with the e-ink display

1. Install system dependencies:

apt install python3 python3-pip libopenjp2-7

2. Install Python dependencies using the requirements file:

pip3 install -r requirements.txt

Alternatively, install dependencies manually:

pip3 install inky[rpi,example-depends]
pip3 install pillow>=10.1.0
pip3 install requests>=2.31.0

• Copy the photogallery.py script and images folder to the Raspberry Pi (e.g. to /home/[username]/eink)
• Remove the example images and place your own PNG files in the images folder
• Automatically run the script when the Raspberry Pi is booted by running crontab -e and adding the following line (change the location of the script):

@reboot sleep 60 && cd /home/username/eink && python3 /home/username/eink/photogallery.py &

• Copy the photogallery-immich.py script to the Raspberry Pi
• Set the required environment variables (you can add these to your ~/.bashrc or create a startup script):

export IMMICH_URL='https://your-immich-instance.com'
export IMMICH_API_KEY='your-api-key-here'
export IMMICH_ALBUM_ID='your-album-id-here'

• To get your Immich API key: Go to your Immich account settings and create a new API key
• To get your album ID: Check the album URL in Immich or use the Immich API to list albums
• Automatically run the script when the Raspberry Pi is booted by running crontab -e and adding:

@reboot sleep 60 && cd /home/username/eink && source ~/.bashrc && python3 /home/username/eink/photogallery-immich.py &

The script will automatically create an immich_cache directory to store downloaded thumbnails.
