I believe you can read and write ufs (it is ufs if it is freebsd) with samba or sharity-light. If the freebsd install works you could also just check out
http://www.freebsd.org/doc/en_US.ISO...ating-cds.html
and if it doesn't work and you have 2 cd drives. You could download the 2nd cd of freebsd which is a live cd and probably burn off the pics on to a disk. If you really get stuck and don't get a better idea here than i have given you. Try asking at
www.freebsdforums.org as there are some very expert/helpful people there and it is a higher volume than here for bsd matters. Good Luck with the pics
edit- if it is a very new install/version(5 or 5.1) of freebsd the filesystem is usf2 which might pose a problem with samba/sharity light
