Can you import pictures from your computer to your memory card?

How do I unlock a memory card for my camera?

• Over the weekend I used a different memory card, when I put my original back in (SD 4GB Duracell) I turned on my Camera(Canon Power Shot SD1400 IS) The screen was black when I pressed the play back button and said "Memory Card Error, Memory Card Locked" I checked my memory card and it wasn't locked, when I pushed the slide down and put it back in it, the whole screen was black and I couldn't even turn my camera on. Any help would be greatly appreciated because I have a few hundred pictures that I haven't uploaded yet into my computer! Oh, and I also tried uploading them and nothing popped up. Usually it would ask me what I wanted to do with the pictures, as in import them. I guess it can't read the memory card? Thanks in advance :)

• Answer:

  Check the memory card again. Make sure the tiny slider on the card itself is in the unlocked position. Double check it is inserted in the camera correctly. If these two things are correct, you have a more serious issue. The card could be bad, or something is wrong with the camera.
