What is difference between jquery lightbox with slideshow and VisualSlideShow?

Q: Hi! Thank you for your products!
Small question - please can you explain the differences between Visual Slideshow and Visual Lightbox ??

A: VisualLightBox app. generates web photo galleries, 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.
