What IS Thinglink? It's a super easy to use and powerful way to bring images to life. You simply find a background image, and add clickable links - basically, 'hotspots' - to the page.

Here's a short presentation I put together for my high school's faculty. We've started to use Thinglink for both student projects as well as teacher created works - one teacher has created a Math summary study guide that she's provided to her students to study for finals!
Finally, here's a short video that explains how to add content, once you have your account set up and have added a background image upon which you can place the links.
