Allowing commenters to add slides
By default, anyone who has been given explicit permission to comment on your VoiceThread can also add slides of their own. Contributors can only add slides. They can’t edit the VoiceThread in any other way, they can’t alter anyone else’s slides, and they can’t delete your VoiceThread. This is a powerful way to build a collaborative VoiceThread.
You can empower anyone who has secure commenting access to your VoiceThread to add slides, as well. To enable this, set the option called “Allow commenters to add slides to this VoiceThread” in your thread settings.
Commenters can add slides by clicking on the upload icon in the bottom-right corner of the VoiceThread.
