We have everything set as you indicated except for the product image SRC we use:
{{dc:post:featured_image_id size=“woocommerce_thumbnail”}}
When your example, {{dc:woocommerce:product_image}} is used it presents the full size product image, which is a bad practice for the archive pages because not only is the image file way too big but the images are also not using the neatly cropped version so it looks like a mess.
What’s the proper way to get the placeholder image to show while also utilizing proper practices for archive images?
