HOW TO SHOW AN IMAGE IN THE FANCY PRODUCT DESIGNER BOX

Hello, I currently am using Fancy product designer on my website so customers can customise cookies that they order from me.

I have a selection of options in the drop down menus (Phrases that are available as standard in standard fonts) 

I would like the customer to be able to click on a selection in the drop down menu and then see it automatically in the preview window (if thats what you call it) I have attached a screen shot of the drop down menu

Can we customise it so that it does that? 

If not how can we customise it?

Regards
