I would like to add pictures that the text question relates to.
Great news! We now support images as well as sub and superscripts (using LaTex) on Multiple Choice Poll options. More info here: http://blog.polleverywhere.com/its-what-you-wanted-image-support-math-equati
Thank you for your patience and enjoy!
This is a much requested feature; that we are planning to implement in the future. For now you can accomplish this by embedding your poll in a PowerPoint on a slide with the images.
