I'm designing a store for my aquarium business. Therefore, my sales categories, briefly, are fish, corals, snails, and dry goods. Within each category, there are multiple sub-categories (i.e. 3 subcategories of fish, 4 of corals, 4 of dry goods, etc) all items for sale would be placed under one sub-category. So on the homepage, each category listed has it's own picture and everything looks perfect. Once I click into a category page, it lists all of the sub-categories properly but without any images for the sub-categories. I cannot find any way to add images to these sub-category boxes. Once I click into a sub-category, then every item has an image associated with it, but the lack of images in the transition page still makes the website look unfinished and I cannot find any way to fix it.
