Hi ,don't mean to interfere with 4gs advice, but not all comps have card readers built in, mine doesn't, I use a card reader that plugs into the USB port,or use the lead that came with the camara, this also goes into the USB port.
But to be quite honest, uless i want to do something special with a photo on photo/shop, then I just take my card, or CD, if I have stored files on CD down to ASDA, or one of the other places that process digital stuff as i find it much cheaper than buying good quality paper and inks,
good luck, ,,,,,pete.
