@Chris-Bosman There are FTP example commands here: https://wiki.fogproject.org/wiki/index.php/Troubleshoot_FTP
You would FTP into your Synology box and just see where that lands you… what is the default directory? Do a directory listing… maybe create a small file there (then later search for where it went) and just do what you can to figure out where you land when you FTP in.
You’d basically symbolically link that default directory that you land in to the actual root of the Synology box. (to my understanding).
There are also other ways… you can symbolically link from the default directory straight to the images directory… and define your storage node path as such.
