This web tool has some really good features and is really easy to use. First you'll be asked to upload the pictures you wish to use to create your story. (Tip: if you want blank pages for just text save a coloured background on "Paint" as an image) On each image you can add a title, subtitle and sound. There is then the "Zoom and pan" option.
By altering and adding new points you can control how the camera will pan across your picture - at the bottom of the screen you can alter the speed at which the camera moves. Also, you can "Choose Label"; this option allows you to add speech bubbles to your picture.
Finally, there are options to download as a movie file or embed into your website/learning platform.
