I think xfire's the easiest and definately fastest way to take and post screen shots. It takes me all of five secs to post a screenie. Just hit
Scroll Lock+S during a game and it will take a screen shot that you can then post by going to your xfire
profile page(I recommend adding to your favorites), clicking on your
screen shots, then
share and copy/pasting the URL to our site.
Most of all,
it does all the time consumeing stuff for you, its great. It sounds harder than it is so if you still have questions just ask me.
