How deep are you in the ESP32 dev? I've found image rendering (the display is LCD, not eInk) to be less straightforward than anticipated.

In my case, massaging images into a specific size and format prior to sending them into the ESP32/Display is easier and more reliable than trying to have the ESP libraries display any arbitrary image.

I haven’t actually started coding yet with the ESP chip. In my case the aim is to pick up a preformatted image from an URL, avoiding all of the finicky formatting you describe. I like the idea of the screen controller as a single function machine just for display, with the backend being a simple GitHub repo connected to Cloud Run via CI/CD.
