ThingLink is one of my favorite tools for playing with media. ThingLink allows you to add links, text, videos, and audio recordings to images. If you embed a ThingLink image into a blog post and allow editing you can have anyone add comments to the image. The comments can include links, text, videos, and audio recordings.
One of the things that I often do to spark students' curiosities and questions about a topic is to present them in an interesting image. To allow students to comment directly on the image I will put it into ThingLink then embed the ThingLink image into a blog post. See the example below.
By using ThingLink in this way I can have students and more than just text comments in response to the visual prompt. To extend the activity I can have students look for YouTube videos and or websites that will help to explain answers to the questions generated by looking at the featured image.
