i have to recover out of themes of some of them.
in an other website, i have done a catalog of my ecommerce autogenerated in pdf.
the duplicated image (the featured image assigned to more than one product isn’t showed.) try visiting:
https://www.planetshopping.it/catalogo

I explain:
i can get attachments by the table wp_post (post_type=’attachments’) but if i have some products with the same thumbnail/attachments i can’t get the image with this system.
i looked for the function wp_get_attachment but i can’t take $attachment_id to pass to this function.
where is stored the featured image of these posts?

you must set permalinks.
