My nikon D70s won't save pictures to my computer

My most recent shots won't save to my computer, the old shots will though. I tried 2 different computers but it still won't work. When I like the files where I save all of my pictures, it will show the old shots but the new shots will only have a file and a picture of a cartoon flower on it.

You didn't format the card before using it
the manual told you to do that
go to google
type photo rescue
