I don't have Nero available to me right now to check, but I see the Nero Vision pack (included with Nero) has the ability to make video slide shows. You can include a slide show as a standard "title" on a DVD, accessible from the DVD "main menu". Go to
tutorials, then look for "creating a slide show".
ps There's even a "save original pictures" option, so that the pictures are saved in PC-readable form on the same disc.
