If you would like to customize your appointments and services with a variety of images that not only make your page more interesting to your clients but it is also a great way of showing off your product or sharing images that describe the service.
To add a carousal of images for that service- open the settings for your service/product.
-Click on Cover Media
-You can add a cover image which will appear if you share that service as it's own landing page. ( make sure to un-tick the Global tickbox)
-You can also add a gallery of images by scrolling down to Gallery and uploading.
Hope that helps!
