Many Linux distributions have a .iso disc image file, which can be used to burn the disc. We can also use them directly under Linux systems.
$ Mount -t iso9660 xxxx ie / any / path / if / u / like -o loop
E.g:
Mount -o loop -t iso9660 / mnt/smb/www/mandrake82-cd1-inst.i586.iso / ISO1
Mount -o loop -t ISO9660 / mnt/smb/www/mandrake82-cd2-ext.i586.iso / ISO2
Mount -o loop -t ISO9660 / mnt/smb/www/mandrake82-cd3-supp.i586.iso / ISO3
