How can I make an interactive photo slideshow that can be put onto a DVD?

I’m essentially wanting to combine PowerPoint and DVD – I want to put pictures onto a DVD in such a way that the viewer can manually scroll through the pictures using the DVD player remote with no automatic timer or anything else. I’ve seen a few programs that might do this, but trial versions limit the number of pictures I can use and I’d rather not pay for the program. Any thoughts?

Thanks,

Cameron
