If you have a yahoo account go to flickr.com and do a search on the camera you are looking at. There are pictures from all kinds of cameras on there and you should be able to see some that have obviously not been edited.
I have heard a lot of good things on the kids fs brand. Not that the picture quality is outstanding, but that it holds up well and the kids like it.
On the adult one. I bought my kids the Olympus stylus waterproof 600. They have several different varities that are waterproof/shockproof and hold up well. The picture quality is reasonably good and the card is small but holds a ton of pictures.
A card would be better to get because she can get someone at the stand to help her. It would be better than using a cable. You want to be careful about what you plug your camera into! A fried camera is no good and more expensive to replace than a fried card. It is easy to mess up something when your camera is plugged into your source.
The higher end kodaks (700 models), the cannons sd models, some fuji's and most of the nikons are pretty good too. Just look at what you think she would be shooting most. For a lot of mixed things and simple kodak is great- what I recommended for my mom who never reads instructions. For dark rooms, events, etc. Cannon is great. For wonderful color and abiltiy to change some settings Nikons are great. It just depends on how it is used. Like shoes, they come in all flavors. LOL
5 megapixels are good, don't need higher unless you want to go fancy and make huge prints. one that has auto and program mode is better. Auto uses flash on most cameras every.single.time. Program lets you pop it up if you want to or if it thinks there is a need for it.
Good luck
