Looks like the extended case matching doesn't work on OSX. Here's a modified version of the case statement if you're running this on a Mac:

    # Set image based on the first argument
    case "${1}" in
        # Image aliases
        ubuntu)
            IMAGE=${UBUNTU}
            ;;
        cent)
            IMAGE=${CENT}
            ;;
        cent5)
            IMAGE=${CENT5}
            ;;
        lamp)
            IMAGE=${LAMP}
            ;;
        ulamp)
            IMAGE=${UBUNTU_LAMP}
            ;;
        # Use the first argument as the image-id
        *)
            IMAGE=${1}
            ;;
    esac
