Eric,
Thank you for your business first of all and welcome to WordPress. The row of image boxes on the home page are part of the theme. The text and images come either from recent posts or from food menu items. In the theme options page, if you’ll go to the Home Page tab, you’ll find the options in the “featured row” section there.
First you can choose to display posts, a menu group, or leave the row out altogether. If you pick posts, you’ll then choose a category as a source for those posts. If you only use one category on your site, then that will be the only option. If you have more than one, you can choose there. Only categories that have posts published in them will be visible.
If you go with a menu group, you’ll need to choose the group from that drop down.
Which every way you choose to go, the image is the “featured image” for that post or menu item. The text that is displayed is the title of that post/menu item.
If you need help adding a featured image, there’s a quick video in our video section about them.
If you need any help, let me know,
Bill
