Custom S2 Layout for Fotobilder

Hi all, I'm creating a custom S2 layout for my fotobilder account to match my custom S2 layout for my Journal. I've run across something that I'd like to get help on.

On the GalleryPage class, there is a member of type Picture[] called pictures from which I can obtain information about the pictures in the gallery. I'd like to print a list of the pictures including the descriptions for those pictures on my gallery page. The problem that I'm getting is that on the Picture class, the member of type string called des is where I'd assume for the descriptions to be, however the documentation says "string des : Description of picture for gallery pages. Not populated by default.", and that seems to be true. The fields are empty when I'm trying to access it from the GalleryPage.

Does anyone know why the fields would not be loaded, and if there is any way for me to get them from a GalleryPage?

much thanks,

Mike.
