It wound up being relatively easy, really. Joomla renders menus as
<UL><LI><A> tags. All I needed to do was extract the backdrop from among the menu images (in selected and unselected condition), set a images because the background in each one of the styles within the Joomla CSS, and voila, it almost looks just like the old site (minus a rather different font, because the text is no more area of the image).
To exhibit a food selection being an image, edit your food selection and choose a picture underneath the Parameters (System) heading (This list instantly populates using the images within the images/tales folder).
You must also set the module for that menu to show the pictures you place. Visit Extensions > Modules, then choose the module for the menu (for example, Primary Menu). After that, choose Other Parameters after which set Show Menu Images and Menu Image Connect to Yes.
