You also have couple of configuration options handy to tweak the component as you wish:

• Show/hide unpublished products
• Show/Hide related product images
• Thumbnail size for the product list
• Sort by product name or SKU
• Sort order ASC/DESC
• Maximum number of results per page
• Legacy/Modern mode - to support older VirtueMart installs using the legacy related products handling mode
• Debug - switch on the debug mode for component only which let you find out what is wrong
