I’m not sure if i get you right, but… HDMI is kind of an one way street. You can’t send any signal / data from your TV to the laptop that way. So you can’t control your laptop through the TV remote. If you hook up your TV through HDMI it becomes a stupid monitor. My best advice would be to get a small wireless keyboard/touchpad combo to connect to the laptop. Maybe a remote control you connect to the laptop will also do.
Easiest way is to use an Indivious instance, if you are on desktop or use the Newpipe App if on Android.

I have a very detailed memory of my great-grandmothers appartment. There are no pictures of this place at all, but i clear remember the arrangement of furniture and decoration. The appartment was cleared and sold shortly after she died. I was 15 month old when she died.
I don’t think that will work. Even a small jpg with under 1mb has to much data to get in one QR code. Not even considering multiple images. You probable can get one small svg icon into a QR code… but what’s the use case anyway?
