As we already mentioned this module has own configuration page available on modules manager page (modules > modules). You can "configure" module main features there, the way of how it behave globally and control the most important settings from addon's workflow point of view
Module to its workflow also uses PrestaShop's default settings of products
As you know - this module displays pictures of products on lists of products like category pages, search results etc. So it will use settings of products. On each product edit page you can upload pictures to products (module will use them) and also associate these pictures with products' combinations (module will use such associations if you will set it up to display combination's pictures).
