What is the blog slideshow?
The blog slideshow is great for photo-oriented blogs.
To start it, go to any blog entry with a photo and click on the little blue magnifying glass on the bottom right of the photo. This displays the Blog Slideshow window, which shows just the photo and the title for the blog entry -- the text is not shown.
"Previous" and "Next" buttons appear above the photo so you can click through all the photo entries in that blog.
