Get one of these Eink frames from waveshare. I have an older version without wifi, so i have to run a python script to e-inkify images on my laptop, copy to the SD card, put it into the frame, but the linked one doesn’t need that.
Since pi zero 2w is just a linux box, you can ssh into from remote and add/remove images from the folder that the screen shuffles through. Heck you could set up an cron job for the pi to hop onto your network and sync a folder on the nas.
And you can ignore the AI thing on this if you want, it’s a neat side thing, not integrated to the display functionality code.
Edit. Oh I didn’t see you wanted very large like 16 inch, I think big eink panels are outrageously expensive still

Whew, by chance i bought 2 16gb pi5s to do some long-planned builds 3 days ago at the old price. Feeling very lucky right now.
I tried to find the price trend for lpddr4, but it’s clear that even at launch prices, ram has been the largest single component cost, since the 16gb launched at $120 while the 2 gb launched at $50, so that extra ram was always a premium. The prices for all (except 1 gb skus) increase about $4 per GB of ram, thats tough.
