Mounting a DVD or CD image (ISO file) virtually is trivial in linux. To do this you’ll need to have superuser permissions, in the example below I’m using the sudo command:

cfaber@sputnik:/dump$ mkdir ISO
cfaber@sputnik:/dump$ sudo mount -o loop DVD-IMAGE.ISO /dump/ISO
cfaber@sputnik:/dump$ df -h | grep loop
/dev/loop1             1.8G  1.8G     0 100% /dump/ISO

As we can see, mount was successful!
