Compile the pictures that you wish to use for your slide show in a folder.
Open Windows Movie Maker. This is under your "accessories" tab on the Start menu.
Double-click the folder containing your pictures. This will open up a browse window. Highlight all the icons in this folder.
Drag the highlighted icons into the illustrated film strip at the bottom of the Windows Movie Maker window. Your pictures will begin to load into a movie. Your pictures will begin appearing in the strip.
Right-click on the strip and select how long you want each picture to display.
Locate the music file you wish to use. Once you have found it, drag and drop it to the beginning of the strip at the bottom of Windows Movie Maker.
Adjust how long you want a song to play by dragging the edge of the clip. You may add more than one song using the same method explained in the previous step.
Save the movie by going to the "File" tab at the top of the screen and selecting "Save to Movie." Your slide show will be saved and ready to view.
