Uhm. I hit the "print screen" key, opened my graphics program (PSP BUT ANY WILL DO), clicked on "edit" then "paste". Cropped it to a smaller size, did my text and arrows, saved it as a Jpeg. Went here http://www.imageshack.us/ browsed for my new Jpeg, Clicked on "host it", copied the "direct link", came back to this thread, hit the "image" button above where you write your post, pasted the "direct link in the box, clicked "OK" and "submit".
Seems like a lot but after you do it a time or two, it just takes a couple minutes to do all of the above.
