I'm also interested, if you manage to make it work please tell it to me.
What I want to do is really similar from the technical point of view, but the end goal is different.
What I want is to use my Kobo as a dashboard for my home automation system. Since the integrated web browser is not able to render the dashboard for some reason, I'm generating some kind of screenshots of the dashboard directly on the server, and now I only need to display them on the kobo.
My first idea was to create a really simple web page on the server with just the image taking all the screen and some js to make the page reload every 30sec to get the last version of the screenshot. It worked, I was able to display the page in fullscreen, everything looked great, but for some reason the kobo seems to always crash after some time when doing that, so I need to find another solution
