I found a free "photo slider" Java script (see below) that will allow participants to move backward and forward through a series of images by clicking on Back and Next buttons on the screen. Can I use this script somehow in a MediaLab questionnaire? I am not sure how to record which image the participant finally selects, but one inelegant way would be to put an identification number in my drawings and have participants type this number as their response. Please let me know if this would work, and if so, how I would incorporate the script into a MediaLab questionnaire that would allow participants to type their answer. Thanks!
