Mainly jQuery and ajax. Store the answer of the questioner somewhere (maybe a global variable, not found), and then use ajax to dynamically pull the next question and related pictures. The last question sends the answers to the server. Return test results and other messy things.

Coordinate front-end and back-end, submit test data, return results

Save the options, refresh the view, and finally calculate the results on the backend and return the results
