Hi,
If you want to show your document as post, the easiest way is to convert your document to a image file e.g .gif, .bmp or .jpeg (don't know if your application can do a save as [ convert to image/picture ])
then identify a website that will host your image.
After you're done with that...you would then do insert image on that URL - web hosting for your image.
something like this -> [ IMG ]
http:// your image url [ /IMG ]
