Return attached post images downloaded from WP All Import

Hi there,

I'm importing posts from WP All Import.

There is few images per post, downloaded during the import.

When WPAI downloads images, it puts the first image as thumbnail.

But, others images are just attached to post in the media library and it seems there's no way to attach image ID or URL to a custom field.

Any idea to retrieve attached post images to render them ?

Thank you !
