I'm sending $15 via Paypal to the first person to PM me with instructions on how I can extract the achievement icons and raw weapon/armor/ability images from the Starcraft 2 MPQ.
the images are probably hosted on the server, and even if you could extract the images, it would be in a "starcraft 2" format that only sc2 could read. but you could try, google winmpq, and see try opening it.
