How do I put the memory card into my Canon Power Shot S50 Digital Camera?

On the bottom or side of the camera there is a little flap that you probably won't notice until you see a slit thing. Open the flap and push the card in face up. Press it in until it is totally inside then close the flap. To take it out push in kind of hard and it will pop out.

open the battery compartment - you usually slide the card in next to the battery.
