My MacBook lacks a card reader.It doesn't matter if your photos are 1MB or 300MB. The fastest way to transfer them to your computer is by the use of the card reader of your computer (or a fast card reader), and dragging them to your computer. You can transfer the photos from the camera to the computer using a cable, but that is more involved than just popping the card out of the camera and using the card reader on the side of your MacBook.
