Wow. Cool. How did you get them? Anyway, i don't think you can attach them, because the size of the files will be larger that the attachment. But for general attaching, just press "Go advanced" at the quick reply option below. Then at the bottom you'll see an option saying "Add attachment" press that and follow the instructions.
Overwhelmed as one would be, placed in my position
Such a heavy burden now to be the one
Born to bear and read you all the details of our ending
To write it down for all the world to see
But I forgot my pen, Shit the bed again...
