For a while I was using the Apache style, I appreciated the simplicity. However, it seems that it does not display the complete index of a gallery with a large number (72) of images. The color hover and framed styles also appear to exhibit the same behavior. All the styles seem limited to displaying a maximum of 25 images in the index. The stranded and supper simple styles don't seem to have this problem. I would suppose that the style's simply aren't providing a link to the next page of images. Unfortunately I can't test this since I haven't gotten fotobuilder installed locally yet.
This behavior is present with Mozilla on WinXP and RedHat Linux (which much slower than 7.2).

I haven't tested it in IE recently but I know suffered the same behavior w/ the Apache style a few months ago.
