Barbara is right on all accounts. There is probably a way to adjust the size of each picture which could give you more pictures with lesser quality, or less pictures with better quality, but we'll worry about that later, that's getting a bit complicated.

Once you have downloaded the pics to your computer, you delete the pics from the card and use again and again and again.

As for printing, as long as the copier is hooked up to the computer, you can print from it. Another option which might give you better prints is to take the card - with the pictures on it to either a local Wal-Mart, drug store camera department or camera shop. They can make prints directly from your card. I think they cost at least $.25 each (US) but they can get good quality prints whereas your copier may not produce as good quality and the ink tends to run into money.

Sounds like you're moving right along, don't hesitate to ask more questions!
