In which database table and column do I need to insert an image path, in order to display product images in wp-admin (not on the front end)? I insert products by query in WordPress, rather than insert products by admin. 

```
$insert = $wpdb->insert( $prefix."posts", array(
    "post_title"   => $posTitle,
    "post_content" => $postContent,
    "post_status"  => "publish",
    "post_type"    => "product"
) );
// select products ID
$select = $wpdb->get_results( "SELECT ID AS productsId 
    FROM " . $prefix . "posts 
    WHERE post_title='" . $posTitle . "'" );
// echo $select[0]->productsId; die();
// insert umage in posts and product attribute meta posts table
$insertImg = $wpdb->insert( $prefix . "posts", array( 
    "post_status" => "inherit",
    "post_type"   => "attachment",
    "guid"        => $postGuid,
    "post_parent" => $select[0]->productsId 
) );

```
