My camera memory card wont work! please help?

So I have a toshiba 4 gb memory card for kodak easy share camera. I used to be able to put the memory card either into my printer or my computer because it has a slot, and I could upload all my pictures easily now when I put in my memory card it says there's only two files on there and those aren't even pictures! how come my pictures wont show up! I've tried everything I swear!
