If you have Vista Ultimate or Home Premium, it's all there, inc. burning the DVD.
Slideshow:
Click this button if your DVD is a slide show of digital photos. In the window that appears, you can add one or more music files to play in the background, specify the number of seconds to display each photo, select a transition between photos (Cross Fade, Dissolve, Wipe, and so on), and choose whether you want the slide show to pan and zoom the photos.
