Click to enlarge

I am creating a little survey that sends a list of 10 questions to a person and they have to select one of 4 answers by looking at the picture included with the question.  Problem is the default resolution of the image pasted into the form is not very big and hard to see the details.

Is there a way to make the image clickable or something like that which will then open up a larger view of the image?

Thanks.
