Although there's no film, the camera still needs a way to store the images. Many models come with built-in memory cards and some offer the option of purchasing additional removable memory. While some of these memory cards are proprietary, it's expected that most cameras will move to a standard card design.

Other models (only the Sony Mavica series as of this writing, but others are sure to follow) save their images directly onto a diskette loaded inside the camera. Quite a few cameras also offer a floppy disk adapter as an option, although that makes it a bit more cumbersome.

Coming into play with storage is compression settings. Most cameras have more than one compression setting, allowing you to save images at higher (using more memory) or lower (using less memory) quality.
