How to put pictures from computer to camera?
* My Camera: nikon coolpix l20 * The image is on the desktop and I need it on your computer * Ive tried to hook up and put on the memory card, when I do see a window with all the pictures in my camera, but when I try to drag the image from the desktop to the window, I can not work
Do not try moving images from your computer to the camera, since cameras are designed to transfer them to the computer, not vice versa! You may end up having a corrupt memory card (and you could lose your other images on the card memory)! Even if you do, may not be able to see through the camera or transferred to another device, you better use some flash memory cards or drivesh move, images to another device.
