I don't take my camera'a out of the field, I pull my cards and down load them immediately on my laptop. I have never had any trouble viewing them on the computer. I also use my personal digital camera to view before downloading or if there aren't many pic's to look at. My laptop won't read the cards through the card slot on the computer, I had purchased a card reader that will accept any memory card as my computer only has a SD slot and I have many cameras with different memory cards....The card reader works well and will accept any memory card and plugs into the USB port....I think it cost me$25-$30...Good luck with it
