I am creating a survey for collecting biological samples from various game species. I would like the user to be able to click on a link or thumbnail image to view a larger image of a tooth aging chart for the species of interest, which is entered in a different question. I understand that I can insert images as notes, and use the relevant field to determine which image will be viewed depending on which species was entered in the previous question, but the image is very large. Is there a way to enter the image as a thumbnail or link so that the user only views the image if s/he wants to do so?
