In the Menu item 'Product Category List View' on the tab 'Product View' I can set 'Upsells' and 'Cross-Sells' (and there image) to 'yes' to see these related products in the product details page.
I do miss this options on the menu item 'Product Tag List View', while this is just another way to show products listed on a page (based on tags instead of categories).
How to make the related products visible in a product page reached by tag listed overview?
TIA and kind regards,
Joris
