Pardon my political incorrectness...

If you can't get it to work under FreeBSD, I'm pretty sure that it works 
under Linux:

   mount -t iso9660 -o loop file.img /mnt

(I'm not sure that "iso9660" is the right filesystem type, but "man 
mount" will tell you.)

Once mounted that way you can use it like any other filesystem.

I actually did this once, but it was years ago.
