Deleting a product, how can I make sure that when deleting a product, the photo of the product is deleted?

Question

Kohana

Hello , how to implement the complete deletion of the product, at the moment after the product the photo remains on the server, how to make sure that when deleting the product, all the photos that are in the product are deleted, deleted from the hosting.
Site on Kohana 3.1
Action for deleting a product:

public function action_delete()
{
$id = (int)$this->request->param('id');
$products = ORM::factory('product', $id);
$products->delete();
$this->request->redirect('admin/products');
}

In the product, each photo has a delete button, but also we will not delete each photo separately, and then the product, I’m talking about what is implemented there when removing a photo from a product, it is deleted from the hosting.
Maybe you can somehow combine the code so that when you delete the product, all the photos that are in the product are deleted.

public function action_delimg()
    {
        $id = (int)$this->request->param('id');
        $images = ORM::factory('image', $id);
        $product_id = $images->product_id;

        if (!$images->loaded()) {
            $this->request->redirect('admin/products');
        }

        $p_db = ORM::factory('product', $product_id);
        if ($p_db->image_id == $id) {
            $p_db->image_id = 0;
            $p_db->save();
        }

        @unlink('media/uploads/' . $images->image);
        @unlink('media/uploads/small/small_' . $images->image);
        $images->delete();
        $this->request->redirect('admin/products/edit/' . $product_id);
    }

Answer 1

get an array of photos and delete them
Can the photo be used in another product?

Answer 2

Why not make it in a table with pictures?
ON DELETE CASCADE
