The new website is only meant for people who started their stays/photos after the 4 September.
I do not believe the database of photos was linked up much prior to that so I would use the old site.
The old site is buggy. You will be able add borders to all photos but it might require you to refresh the page or log out and back in.
On the old site go to the help section and under one if the topics is a link for missing photos. Use that form and they will trace the lost photos. I have never had them not find them.
