Thinglink is a service that I have used and introduced to teachers for years. It’s a great tool for creating interactive images as I did here in a blog post about using interactive images to summarize field trip experiences.
Today, Thinglink sent an email to users of their free Thinglink EDU service to announce a major change to the free plan. Beginning on December 15th, the free Thinglink EDU plan will no longer support the option for teachers to create and manage their students’ accounts. That feature will only be available to those who subscribe to the pro or premium accounts.
While we’re on the topic of interactive images, you might want to consider trying Formative or Wizer for creating interactive images that include quiz questions.
