Hello,

I have a K4 with broken "page" buttons and I want to use it to monitor some parameters.

first thing to do:
It should load a picture from a server (every one or two minutes or so) and bring it to the screen.
My Idea is to do get the picture with wget controlled by an entry in the crontab. But.. is there a command to display the picture on the screen?

second:
It should work while the power is on (USB Power supply is plugged in). Without USB power it should go to sleep after 5 minutes.
No Idea so far.. Is it possible? any hints?

i've looked a lot in this forum but I didnt find a solution.

What I have done until now:
Jailbreak and SSH access via WiFi. No problems with that

I hope someone can help
