Hi UncleCheese,
The xml link is http://supportact.com.au/ss/debonairs-nsw-gallery/xml
The page displaying the swf is http://supportact.com.au/ss/debonairs-nsw-gallery/
As you can see the thumbnail for the album is fine just the images inside. If it is of any use this page was already created as an ImageGalleryPage page type that I just changed to the SlideshowProPage page type.
Thanks again.
