This reply assumes the OP is working with a professional client and has limited or full network access:
Great advice, but if the client wants the sharing software within their realm (as most clients would want to centralize resources and localize management) install any file sharing daemons on the server. Most clients use Windows File Share (SMB). If they need a suggestion on a server based share, try open source SAMBA - works great, secure, easy setup, restrict by IP, tie into existing LAN workgroups, etc.
Then on your Mac when in Finder click on "Go" -> Connect to server and you can type in smb://servername/share - after being prompted for any passwords, user info or workgroup. Or type in the full network name:
smb://WORKGROUP@ServerName/ShareName
Either way it ends up as a very convenient mounted drive available to your image app.
This method means no extra software is installed on your Mac.
