If you have special advertising or affiliation banners that you'd like to add to your store, you can add them easily to the store using the Header & Footer section.
To get to this area of the Shift4Shop Online Store Manager,
Log into your Shift4Shop Online Store Manager.
Using the left navigation menu, go to Content > Header & Footer.
From here, you can use either the Global Left Banner, Global Right Banner or the Global Footer sections to add your banners.
After adding your logos, be sure to enable the global banner you selected to make sure it displays on the live site.
