Display thumbnail in browser

[Vinculum]

I am working on my own farm management tool where i extract data from the printer by interpreting the JSON data from rr_model.
What I want to do is display the thumbnail in a webbrowser. I can see the gcode filename, the size and offset of the thumbnail but i can't extrapolate the actual image datastream. The only way i can get it is by sending M36.1 command in the console of the WDC. But that I can't see from my webpage.

How can I get the thumbnail adres or data?
