Richard Byrne shares a short tutorial on using ThingLink to create interactive images. ThingLink is now offering educators and students free accounts (create up to 50 images for free) or a paid plan with 500 images at a discounted price. How might you use ThingLink. He suggests that it "could be used by art students to identify and tag important elements of a picture, drawing, or photography...could also be used in history classes to have students identify important places in a battlefield like Gettysburg." What ideas do you have for using this tool?
