How can I get a picture off my camera onto the computer?

How do i get the picture i've compressed off my memory card if the camera and the computer say they aint there?

• ive compressed videos and pictures on my camera but it wont download to the computer. the camera and the computer say there ain't anything on there but i can take it to a store and print the pictures off and everything is still there. the camera guide tells you how to put it in to low level format but it dont tell you how to retrieve them. help me please

• Answer:

  Low-level formatting is not "compressing the pictures". A low level format will wipe everything on the card. It is an option seldom used...it's good for the card to do it once in a while but will delete everything on it. Totally. Unrecoverably. Re-read that manual and the warnings about using the low-level format. I don't know what you're seeing at the store but it's not on a low-level formatted card.
