Thinglink is a neat service that allows you to make any image on your blog an interactive image. To do this you have to install the Thinglink plug-in (available for Blogger, WordPress, and Tumblr). Once you have Thinglink installed (it took less than 30 seconds on Blogger) you can tag and label anything in the images on your blog. Your tags appear as simple dots on your images. Whenever someone places her cursor over a dot in the image, the information in the label appears. You can include descriptions and or links to more information in each tag. Watch the video below to learn more about Thinglink.
Applications for Education
Thinglink could be a good way to have students take group blogging to a new level. Students working on a group blog could upload images then work together to add more information to the blog post in the form of image tags. One way that I'm thinking that this could be done in my US History classroom is to have students upload pictures representative of concepts from the Industrial Revolution then tag different parts of the images to link out to further explanations and examples.
