Download the medium images to a folder to your computer. (not thumbnail size)
Go to Animoto, (Be sure you are signed in) and Click #1 "Images" and upload your images, rearrange them and follow the on screen directions and ideas.
Now it is time to add some audio. Click #2 Audio. You have two choices - either your own music or voice you created on your computer or just click music to use stock music from Animoto.
Option #1 Just add music from the Animoto online library
Option #2 Research some background information about the images you choose. Use Garageband to record a 30 second spot, save and upload.
Finished with audio - move to #3 "customize a video" and now you are done!
