Clear Form Button Won't clear Pictures

I created a form with a "clear form" button but the button will not clear the " java script image icon" pictures I add to the form. I intend to use this form for inspection reports on a daily basis and want to be able to clear all the text and photos added to the form. The only way to clear the photos from the image icon is to go into the properties of each icon. Is there a way to enable the "clear form" button to clear all the data that is input into the form?
