According to Wikipedia:

An ISO image is an archive file (also known as a disk image) of an optical disc in a format defined by the International Organization for Standardization (ISO). This format is supported by many software vendors. ISO image files typically have a file extension of .ISO but Mac OS X ISO images often have the extension .CDR. The name ISO is taken from the ISO 9660 file system used with CD-ROM media, but an ISO image can also contain UDF file system because UDF is backward-compatible with ISO 9660.

And if you have one of those images, you can use it under Linux in two ways.

1. Burning an ISO image
2. Mount the image itself to use if from the disk.

Here we will see how to do the second one.

Create the mount point

sudo mkdir /mnt/iso_image

Mount the ISO image in the mounting point

sudo mount iso_image.iso /mnt/iso_image/ -t iso9660 -o ro,loop=/dev/loop0

or

sudo mount -o loop iso_image.iso /mnt/iso_image

It is good to define it as read only ro as that is the way CDs work
