When I use interpreter.chat(stream=True), in what scenarios will type return 'image'? about open-interpreter

[chasing1874]

Or when OI generates a chart using MatPlotLib I'm trying to find a way of saving it as a .png and returning the image path in the message thread so that I can display it in a tag on the frontend.
Ideally it would be returned like so: {"role": "assistant", "type": "image", "content": image_path}
How can I acheive this? Do I need to extend the Interpreter class with an extra method or can i achieve this through system prompt?
