If you've loaded AH in the default location, you'll find the screen shots at C:\Program Files\HTC\Aces High II, labeled as ahss0.bmp, ahss1.bmp, and so on.
To "put up" screen shots, I'm assuming you meant to post them on the web. Open the screen shots with any picture editing program... a free one that works well is Gimp, do a google search for it....Save the picture as a jpg, or gif at a location where you can find it on your computer....MyPictures in the "document" folder works well.... Go to
PictureHanger.com and get your self a free account and follow the instruction there to up-load your pictures. The reason you have to save the pictures as a jpg, or gif is the format makes for much smaller files to up-load/down-load. Most free site that house pictures don't allow bmp format as they take up a lot of space.
