There isn't a function built into ShopSite that will do that. Images may be included on a page or product by using the html for the image url in a text field which ShopSite wouldn't know about. There are also other places where images might be used such as the store logo, buttons for shopping cart, registration, etc. screens that may be in the media directory but which are not used by products or pages directly.
So we don't keep track of whether an image is used or not.
