I'm working on a small project and I need my raspberry pi (model 2B, rev a01041) to send a very simple image to a little screen (probably 10x5cm).
Unfortunately, I've always thought I'd never have the use of a screen so it is installed and configured in headless mode, accessed by WiFi SSH connection (using Kitty, a Putty-like Windows application).
How could I send a refreshable image to the HDMI-connected device?
I'm thinking of a light web browser and a simple HTML interface but have no clue where to find info.
EDIT1: i tried installing the gui (pixel), but controlling it with SSH is a lot harder than I thought. All I can find is about X11 forwarding, which is the opposite of what I'm looking for.
EDIT2: i also tried pygame, which is very interesting but would require me building the GUI in python which is not exactly what I want.
