Yes, you can give specific background images to navboxes with CSS and making sure the navbox element (table, div, etc.) has a specific CSS class or id.

You can test CSS by putting it in Special:MyPage/wikia.css (on the wiki where you want this to work) and only you will see its effects.

Here's some example CSS (where your table has  like  ): table.potions { background-image: url("potions_nav_background.jpg");
