What is a CD/DVD Image

A CD/DVD image is a file that contains all the information necessary to make an exact duplicate, or clone, of a CD or DVD. Images are created by software that writes every bit of information contained on a CD or DVD into a file on your computer. This file can then be made available for download so that other people can make an exact duplicate or your original CD or DVD on their own computer.

Now do not think that you can simply go out and buy a CD and then create a image of it for your friends to download and write to a CD. Most commercial CDs these days have a copy protection on them that makes it difficult or next to impossible to duplicate. There are, though, certain CDs that you are allowed to freely distribute to friends. 

Different types of CD/DVD images

There are many different types of CD/DVD images that can be found available for download. The type of image is usually dependent on the CD Writing software that was used to create the CD/DVD image. A very common image format that is used on the Internet is anISO image. This image format can generally be read by almost any CD / DVD Writing software on the market. The type of a CD image is usually determined by the extension of the filename. For example if a CD image was called linux01.iso, then the image type for this file is most likely an ISO image
