Please use the newest package SPPC Lite 2.0 uploaded on 6th November 2016.

Do you want to display product image or cart icon for product result?
But this option is enable by default so if you haven't picture for products from dropdown maybe you haven't installed the right version :
Store Search with Image (BS) : http://addons.oscommerce.com/info/9504
