Hopefully you are a Mac person. The principles of disk images are the same,
but I don't know how to use PC images.
A disk image is a file format for distributing software that preserves
ALL the info present on the original disk. For example, system disks
contain certain information in the boot blocks that is not preserved
if you make a simple copy of the disk (which really only copies the
visible files on the disk).
Apple has a disk image tool called DiskCopy 4.2.
Many Macintosh utility packages make their own disk images--in addition,
all support DiskCopy 4.2 images. DiskCopy 4.2 is available free from
Apple's ftp site, ftp.support.apple.com, and probably also their WWW site
(http://www.support.apple.com, I think--don't promise)
