The college uses a separate IIS server for image and document file distribution.  This is done for the following reasons:

  1. The practice preserves space and ensures that a file is updated throughout all sites.
    1. File de-duplication.  Instead of uploading an image to multiple sites, it can be linked to the IIS server.  
    2. Resource sharing.  Once a file is created and added to the IIS server, any content manager can use it on their site with a simple link.  
  2. The files are easier to update
    1. Simply go to the mapped drive, and overwrite the original file.
    2. In Wordpress, you cannot simply overwrite the file.  When you upload a file with non-unique name, Wordpress automatically appends your file name creating a second file.  You then have to change the file link on the page too.
