You would use the ISO files for burning a CD or DVD to boot and install FreeBSD.
The larger DVD1.ISO file has more pre-built software packages on it to install
after you get the basic install completed; the other ISO files are smaller because
they expect you to be able to connect to the internet to download the needed
extra parts during the installation.  DISC1.ISO has the basic FreeBSD
system parts on it, but optional things must be downloaded from the internet;
the BOOTONLY.ISO is very small because it contains just the minimum to boot
a machine from a CD/DVD, and everthing else, including the base system, must be
downloaded from the internet.

The IMG file is basically the same as the DISC1.ISO, but is for loading on
a USB memory stick and used in machines that allows you to boot from a USB
memory stick.
