Can I display multiple images of a product on the product page?

It is possible to display more than one image of a product on the product page. You would need to go to Site Name > Catalog > Products > [edit Product] > Artwork tab. 

From this page, you can upload as many images for the product as you would like; however, one image would be displayed as the primary image while the others would appear beneath this image within smaller thumbnail images.  To choose the primary image, click the star icon beside it.  The screenshot below illustrates this:

You may also choose to add more images in the product description page by going to Site Name > Catalog > Products > [edit Product] > Description tab
In the long description, you can add more images via the image manager.  See the screenshot below to see how to access the image manager.
