hacked /files_ip for now, this whole page is a bit of a mess, not sure we keep it - and its a kludge to assume its in the file_ip path -- only will work if img is in import path and we are viewing in flat mode, but at least this means we dont break the app, just get a confused viewer message. Also use tmp_locn rather than face.locn for viewlist to fix BUG-82
