I am looking for an option where the student can respond to the question by adding a photo? Adding a picture is possible with Disqus. However, I do not want to the other students to view the responses. Are there any other options?
With our built-in Discussions feature, students are able to respond with images but this would be public to other students.
For private assignments you do have some options, discussed in this thread: http://help.thinkific.com/support/discussions/topics/313402
I hope that helps, and feel free to get in touch with our support team directly if you'd like to discuss your plans in more detail :)
