Fotobabble is a free service that allows you to quickly turn a picture into an audio picture story. Using Fotoabble is easy, just upload an image to Fotobabble, allow Fotobabble to access your computer's microphone, and start recording your voice. You can comment on your photo, explain what's happening your photo, or tell a story related to your photo. The Fotobabble iOS app is just as easy to use as the web version of the service but with an added bonus of visual effects editing.
