You can reuse the card if the new camera takes that same type (SD, Compact Flash, etc.) of card.
Keeping the old photos on the card is not a good idea.
You need to format that card with the new camera.
A format will delete any photos on the card.
Copy the photos to your computer and then burn them to a CD for backup.
