I took some picture on my Nikon D50 without the sdcard, and they are stored on the camera's internal memory, and I have looked through the menu and through the manual, but cannot find a way to transfer onto my computer. I have plugged in with USB cable, but this only shows the photos on the SD card, which shows up on my Mac either this way or by plugging card in directly to side of iMac 21". Any help would be much appreciated! Thanks in advance. C

use it anyway

Try to load Nikon Camera Control Pro 2 from Nikon sites.
It\'s free for 30 days.

Remove the memory card and you should be able to see them on the camera. Bear in mind that the camera doesn't have much internal memory, only enough to hold nine pictures at full resolution and best quality.

No. Without a memory card the camera stores the last picture taken only so you can view it to verify proper operation. It overwrites the previous picture, and it disappears when you turn the camera off.

You NEED a memory card if you want to save the pictures. Sorry if that wasn't the answer you wanted to see, but that's the way the camera works.

R10 is not a error code, it tells you how many pictures (on average) the camera can shoot before it has to stop and clear its internal memory by writing to the SD card.

Is there a card in the camera? It will not fire without one. Also, if you have taken 20 or 30 thousand exposures, then the electronic switch (not the button on the top) that fires the camera may be worn out.

Sorry, no. The camera is entirely reliant on the memory card to store images.

Either the camera or the memory card is faulty. Try another known good memory card to work out out which item is at fault. If it's the camera then it needs professional repairs, if it's the memory card then buy another.

Never, ever, format your memory card in a computer or external card reader, reformatting should only ever be done in-camera with a fully-charged battery.

1) There's a "Copy" entry in the playback menu that will let you copy pictures between the internal memory and the memory card. Display the playback menu by pressing Playback (the right-pointing triangle) and then MENU. In my copy of the manual, it's on page 94.

2) Consider NOT using a driver at all. The best way to download pictures from your camera to your computer involves removing the memory card from the camera and plugging it into a card reader (either built-in to the computer or connected via USB or FireWire). This is likely to be faster than connecting the camera to the computer, and won't run down your camera's batteries.

Once the card is plugged in, it will appear to your computer as a removable drive. You can use the operating system's drag&drop facility to copy pictures from the card to the computer's hard drive, the same way you copy any other files. Or you can use Nikon Transfer or any other photo cataloging program.

You can copy pictures to/from internal memory by selecting Copy from the Setup menu.

do you have a usb cable to connect your camera to your pc?
Then generally by pressing the power button once the usb cable is connect, your pc will recognise your camera and then follow the onscreen instruction.

Your D40 has no internal memory. The camera can take a shot, and even show you the image on the LCD, but is not actually saved anywhere, unless a memory card is present. There is a way to prevent the camera from firing without a card. It is in the setup menus.
