Here's a sample SAMBA share (put this in your smb.conf)

[htdocs]
Comment = For the GIFs
path = /usr/local/etc/httpd/htdocs/gifs
writable = yes
public = yes

That will get you there quickly until you understand SAMBA better.

Take the time to understand it - it's great! You'll swear by it instead of at it (NFS anyone?)
