Hey Kris,
I was able to log in anonymously and upload the two files into the
upload folder. The file names are Session with Mask Data Issue
(tiff file).ses and Session without MD issue (img file).ses .
However, when I tried to upload the files to the ForKris folder,
it would not allow it (even if I login again anonymously) saying I
wasn't authorized to access the server. Anyways, the files should
be there in upload folder. Let me know if you need anything else.
