Adding a singe image to a product is easy. Adding additional images can be confusing.

To add additional images to a product, find your product in the Product list in the backend of your website.

 In the "Media" column, you will see a small icon. Click this icon. On the next page, you will be able to add more images to the product. You can also add other types of media such as a PDF.

That is all there is to it.
