Tricky setup an images folder vs IIS


I have an interesting and challenging design question.

I have a web application under iis and server is under VPN.

This web application works fine and lately i added a module which reads HTML files in another drive (not under iis).

Now, a customer needs to upload some html files which refers relative path for images in that folder with those htmls

And this fails as images folder is not under iis and i don't want to put those files together with this web application.

Now, what should i do? How can they upload those files?
1) Is it possible not to give access for ftp? This customer should have limited access.
2) Setting up a network share in which the images are in a shared folder? The network share idea fails as the machine is not in the same domain.
3) Uploading files to another images folder in IIS via button in interface? No, we don't want that.
4) Uploading via ftp? We don't want to open a port for that customer.

Am i missing any scenario? Our aim is to give minimum access to server itself. Any brilliant scenario option?

The html links need to be url's so either give the client access to another web folder (could be any one of a gazillion online storage providers) and tell him to change the links to absolute or mount another storage device in a folder he already has access to and lock it down.

a virtual directory can reside anywhere it doesn't have to be under c:\inetpub\wwwroot  but you do need to edit the ntfs file permissions of the target folder.
have you considered allowing webdav for that user and that virtual directory.

Thanks. The thing is that the other server is not even in the same domain and in vpn. Would Webdav work even with different domains and even if the server is not under VPN?
Davis McCarnOwnerCommented:
WebDAV is very similar to FTP; but, is a more modern spec and, depending on the O/S running on your web servers, may need new modules added to support it.
Either way, if you allow your client to place their images on a different server, they will just need to change their HTML to absolute URL's rather than relative.
