How do you download pictures from your SD memory to your computer?

You need to have a SD card reader, either internal or an external one that plugs in to a USB port. Or just use your camera as the card reader if it plugs into your computer USB port. Insert the SD card, find the drive number for the SD card reader (or camera) using Windows explorer or whatever method you use to work with files. Then just drag and drop to whatever hard drive folder you want the pictures in.
