You mean an ISO9660 image? Use an md(4) device. See §16.12.2 of the handbook.

First create a file-backed md device:

# mdconfig -a -t vnode -f diskimage -u 0

Then you mount it somewhere:

# mount -t cd9660 /dev/md0 /mnt

When you are done with it, unmount the filesystem and then detach the md
device:

# umount /mnt
# mdconfig -d -u 0
