Hello @saintaardvark, thank you for the time trying to help me.
I understand now a little better why I couldn’t have photos. As you mentioned it would be much more convenient to type the URL directly in the KIOSK web interface, but the RPI will be installed at my Grandpa’s house (without Config mode, without keyboard). He’s 96 years old, I can’t ask him to do something to change the mode
So I will have to change it for him and I will probably do it through the balenacloud dashboard. I’m even thinking that finally, the easier (but not best quality), would be to share my own desktop with Jitsi, to show photos.
And now, a last problem is emerging as I finally received my webcam Papalook af925. This device is working fine on my computer (Ubuntu 18.04). On balenaDash, the video is working fine, but I can’t have the sound working (“Audio error : could not start audio source” can I read on Chromium).
You can see below some lines of the dmesg command when I plug the webcam :

I see a warning. Can it be the reason of the problem ? By the way, the audio device seems to be registered at the last line of the dmesg…
Thank you again for all your support.
