Dougout,
To save screenshots hit menu twice, go to system and then to screen capture. Highlight the blue dot and exit. From then on when you hit the power button you will take a picture of what is on the screen at that moment. This will continue until you go back into the menu and uncheck screen capture.
Then if you want to save these screenshots to a card and look at them on your computer or post them on a website, insert a blank card into the outside card slot and hit pages. Go to Files and hit enter. Go to Screenshots and hit enter. Then export them to the Memory Card and then they are saved to the card. You can select the card in that menu and view what is on the card to make sure they are there.
