plssss help me. i lost some pictures from digital camera and i must replace it back from the pc, the camera is Canon DIGITAL IXUS 800 IS

Connect the camera to the computer & turn it on. When the Camera Window pops up, DO NOT select any of the options to download pics. Instead, click on the "Set to Camera" tab. Under this tab, click the "Uploads images to camera" button, and off you go!

Hope that helps!

by using a USB provided wid the camera
