<< By the way, I was thinking if I can get some of my desktop wallpapers into the compact flash memory card via the adaptor, so I could view them on my digital camera. Is it possible? >>
Yes. You can either get a CF adapter or a USB CF card reader. Do you have a desktop or laptop? I'm asking because you'd need a PCMCIA slot to use the adapter and these are usually found on laptops, not desktops. If you have a USB port, the reader basically turns the card into a mobile drive. You can download anything to it and transfer it if you want. Think of it as a portable storage solution like an external zip drive. Of course, you will only be able to view the images on your camera if they are a supported format (TIF, JPEG, etc..)
FWIW.. I have a 128 mb Smart Media card with a SM USB reader and a PCMCIA SM adapter. With the 128 mb Smart Media card, I basically have a small portable drive that I can use for basically anything. It's like having a small zip drive.
