If you're new to Windows Movie Maker, creating a photomontage is an easy way to get started. In this project you'll learn your way around Movie Maker, and will end up with a video that's fun to watch and share.
To start, collect digital copies of the pictures you're going to use. If the pictures come from a digital camera, or if you already have them scanned and saved on your computer, you're all set.
For print photographs, either digitize them at home with a scanner, or take them to a local photo store to have them professionally done. This shouldn't cost too much, and it's worth it if you're dealing with a lot of pictures.
Once you have the pictures saved on your computer, open a new project in Movie Maker. From the Capture Video menu, choose Import pictures.
