Sorry I can't get what is your point.
Your result that the relative path is treated as in temp directory is looks like on server import/export path situation.
That is true for the WebDirect implementation. I currently use an HTTP:// path for the images on another web server. I would like to be able to consolidate them onto the FMS, so I still need a relative path to get to the images. Having an externally hosted app, I don't believe that I have a consistent full path to the directory with the database files.
