I've responded via email with some screen shots. Am including text from email here for the benefit of others reading this post.
The short answer is that there is no picture question type, however there is a way you can give users a choice of images by combining a radio question type with a helptext question.
The way I've implemented about is with two questions, the first one a helptext question type that includes the images, and the second the radio question type that includes the options.
Basically, you enter the question in here, choose helptext question type, and insert the images.
The section question is a radio question
This contains the selectable options.
I've also suppressed the question, to make these radio buttons appear to be part of the previous question, set horizontal label to yes so the options will be displayed next to each other, and set a CSS class to make it easier to style these.
Then in the survey category, I added some CSS styles to make it look better.
Anyway, I hope this solution helps you. You can try it all out in the free trial version (fill out blue form on our homepage), so that you can see if this will suit your needs.
