RE: SD Cards...
Most of the first digital cameras used either SD (secure digital) or CF (compact flash) cards. They are not compatible with each other. You'd have to figure out what type of card your wife's camera uses...it should say on the card itself if you pull it out of the camera. If it is an SD card, it will work in your game cam. SD cards are pretty inexpensive nowadays. You can get a 1GB card for about $25-30. With your camera (2MP), you'd be able to get a few hundred pictures on a 1GB card.
