I'd like to run an experiment in which 64 images are presented (1 at a time) and participants rate their preference for the image on a slider scale, and I'm wondering what the best and cheapest way to do this is? Are there some good, free software programs that I can use? I've looked at things like SurveyMonkey and Question Pro but have not found something that seems to work. I don't have any coding knowledge so I'd prefer not to build it from scratch.
I have been using TRUE and it seems quite fine. There is free access to TRUE online version.
