How to unlock my camera samsung i8, all the button cannot function...

your display is turned off in the menu..

You don't need a driver.
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 any photo cataloging program, such as Windows Photo Gallery or Picasa.

you could buy one off the web im pretty sure like the samsung site or ebay.

Will it work on another computer? If so, it's probably a corrupt driver. If the camera is working fine, you may want to just use a memory card reader instead. They are inexpensive and read pictures faster than the camera itself. It is an extra step to remove the card each time but is less than a new camera.

Consider NOT connecting your camera to your computer.
