I work in the graphics department for a real estate brokerage, and we deal with a lot of photos. Agents take the photos, upload them to me, I touch up and standardize the photos, then I add them to an in-house server for future use by the graphics dept.

I'd like to make the "sanitized" photo files available to the agents to use when they want, but I don't want the agents poking around the graphics department's files (things get misplaced, renamed and messed up in a hurry).

What would be perfect is if we could create a read-only "mirror" (correct term?) of that server that could be accessed by the agents as needed, but which wouldn't feed back into our "sanitized" file system.

Edit: I'm looking for an automatic solution... manually posting the files to two separate locations seems like an inelegant solution when working digitally.

Edit: I'm trying to avoid any access barriers to the public (dirty) file system (however it's finally implemented). There are 40-50 real estate agents who need to access these files, half of whom can't reliably download an email attachment.
