I have a single folder with 38 images named 1.1.jpg, 1.2.jpg, etc. Lightbox (using Fast Gallery & Imagecache) correctly shows two pages of thumbnails, with 20 images on the first page and 18 and the second. But the slide show for the first page only presents the 20 images on the first thumbnail page and likewise the slideshow for any images on the second page of thumbs only shows the last 18 images.
