Controller

foreach($array['posts'] as $scrapeData){
        $product = new Product;
        $product->id= $scrapeData['post_id'];
        $product->description = $scrapeData['text'];

        $product->save();
    }

    foreach($array['posts']['links'] as $datalink){
        $images_links = new ProductImage;
        $images_links->link= $datalink['link'];
       
        $images_links->save();
    }

You have to move your second loop into the first to iterate the links :

     foreach($array['posts'] as $scrapeData){
        $product = new Product;
        $product->id= $scrapeData['post_id'];
        $product->description = $scrapeData['text'];
        $product->save();

        foreach($scrapeData['links'] as $datalink) {
            $images_links = new ProductImage;
            $images_links->link= $datalink['link'];
            $images_links->save();
        }
    }
