The first line is a shell command we've issued. I've piped it to grep to output only images containing 'centos' it their names, otherwise the list would be too long.
For every image you see its name and id, for example for CentOS 5.3 (64-bit) w/ None id will be 1532. Please remember it because you will need it if you're going to use this image.
