One option is to use the Tool Tip to allow respondents to “hover” over the small MaxDiff item image and make a larger version of the image appear. Lighthouse Studio has two ways to add a Tool Tip, one is a built-in Sawtooth Script function, the other is a pair of CSS classes. You can find the details here: https://sawtoothsoftware.com/help/lighthouse-studio/manual/additional-function-details.html
The other (faster) option is to use the Image Popup/Magnific Popup question from the Question Library (https://sawtoothsoftware.com/resources/question-library/image-popup
). The Image Popup question adds the Magnific Popup script to your survey which will automatically make every image “clickable” and “zoomable”. The benefit here is that you don’t need to add a tool tip to each individual image. By default, the MagnificPopup question type will only add the zoom functionality to other questions on the same page, but once you’ve added it you can copy the script from the Question Footer and paste it into the global survey Page Footer to add the functionality to every page in the survey.
