9Slides is a wonderful site for create a slideshow (or uploading one) and syncing video/audio to that. Also, what makes 9Slides so nice is how it can be used for professional development and even track usage stats. Another nice feature is the ability to use 9Slides on a mobile device such as an iPad.
I highly recommend checking out 9Slides by clicking here!!!
