If you don't want to carry a laptop computer when you travel or if you like to go out and take a lot of pictures on weekend afternoons, consider adding a portable photo storage device to your camera bag. You'll be able to download your photos to it directly from the camera's memory card so that you can reuse the card as many times as you like.
Portable photo storage devices don't all work the same way, though; some store your images on little hard drives and some burn them to disc. If you already own a gadget that can store digital files -- such as an MP3 player, a thumb drive or a portable hard drive -- but don't have a way to connect it to your camera, an inexpensive USB bridge might be able to turn it into a photo storage device.
To figure out which one will best meet your needs, take a look at our comparison charts for a rundown of the pros and cons, the key specs, download speeds and battery life of current portable photo storage devices.
