I love the new cooliris integration for gallery slideshows. However, I was disappointed that the slideshow only included images from the current album, not sub-albums.
This patch adds sub-album images recursively to every applicable slideshow. Also, it enables the "view slideshow" link on all albums with items.
I'm sure this is not a perfect implementation, but I think this functionality would be useful to include in future versions of the gallery.
This has been tested on my gallery site. It worked well, even on my top-level album with 2500+ images.
