How to make a large Youtube video with only one picture?

I don’t want to use 30 or more photos for one video. And i don’t know how to make a large music video with only one picture of the album, or a picture I create. I’ve seen You-tubers do that but i don’t have a clue on how to. Can somebody tell me how? Windows Movie Maker can’t do it…
