loading a file into the kneeboard

Hi, is there some ways to load a text file or a image file into the kneeboard so I can read it? I read somewhere that there is a tweak you can use to turn it into a web browser. maybe it will work too for a local file instead of some page on the net? What i wanted to do its to able to read all the fly briefing on the lessons (instructions and maps) that i print out into a file and that I can view them during the simulation.
thanks
