There is an option depending on what operating system you are using, where you can place a check mark in a box that will do it for you automatically whey you upload the pictures to your computer. Also you can do it manually by getting into "my computer" or "computer" (again depending on the OS) and while the camera data cable is plugged into the computer, and the camera is on, the camera/memory card should show up with a varying file name with all of your pics in it. Either delete the entire folder or the pics inside. Hope this helps.
