Difference between jquery lightbox alternative and VisualSlideShow

Q: I recently purchased one of your product - VideoLightBox. And I am very happy with it. What is the difference between your Visual slideshow and Visual lightbox?

A: VisualLightBox app. generates web photo galleries where the images appear in a pop up window.
VisualSlideShow app. generates slideshows, images appear with transition effect. Slideshow doesn't appear in a pop up window, it has a fixed position on your page.
