I forgot what program you use to take screenshots
You can use Xfire. But there are numerous other programs. Use google.
I didn't make it!
While ingame press "Print Screen" or PrtScn key on your keyboard. Then open up MS Paint or some other image program and goto Edit and Paste.
Or use one of the various programs out there. Fraps is popular as well.
Yeahs Fraps is pretty popular.
You can paste the screenshot (taken by PrintScreen button) into any image editing applications...ms paint, fraps, snagit, imageready, paint.net, photoshop, painshop, all .....shops, except the one on corner down the street..;)
