Open your Windows Explorer (NOT Internet Explorer!) - go find your Aces High game directory, where ever you installed it to - default is C:\Programs\HTC\Aces High II. In that directory, you will find the files as ahss##.bmp. Double click them to open (Usually Windows has SOME image viewing program that will display them - if all fails, Internet Explorer or Paint do the job).
PS: If you cant find the installment, let your Explorer do a search for aceshigh.exe. This file will be in said directory.
