They are still there on the file sytem but I'm not sure why they are not showing up under your gallery. It's possibly related to having to recompile php recently. I downloade everything under your directory and I'm uploading them to
Index of /files/members/sang. It says it will be about 40 minutes before it finishes. If you see a file called Boz.zip that means it has finished, otherwise it will read something like pureftpd-upload.
