iDVD slideshow issue


I've read and read and I can't figure this out. I am making a DVD to play at carshows showing the restoration of my musclecar. iDVD seemed perfect until I ran into the 99 picture limit per slideshow. I have about 250 pictures I would like to autoplay without having to press buttons, etc.

The problem is, I can ony get ONE slideshow (ie, max 99 pics) to run ..then it defaults back to the main menu where you can pick the next slideshow, but I would like to link all the slideshows so they play one after another without interuption.

Is this possible, and if so, how do I do it??
