Memory card How do I delete the pictures off the memory card so I can reuse it

You can use the camera to do this, but it's slightly different on every camera. You'll need to put the camera into the picture review mode, and the most have some sort of delete or trash can button on them. If you post your model I can be more specific about it.

Another way you can do it, is if your printer or PC accepts the memory card you can remove the card from the camera and plug it into the computer / printer (make sure the printer is turned on if you are using it!). The open up "My Computer" and you will see the card under removable storage. Double click on the drive letter and then highlight everything and hit delete.

All done!
