Some time ago we posted an article on creating online timelines using a tool called Dipty, which allowed you to create, embed and share free image, video and audio timelines online. This was a very useful tool for teaching and students projects. It has since come to our attention that despite millions of users, this tool no longer exists. However, this article lists some alternatives, and discusses the reasons why Dipty is no more. Thank you to the author for getting in touch and providing such a useful list.
