You need to pass .url

{% for i in product.productimage_set.all %}
<figure >
    <img src="{{ i.image.url }}" alt="product image"/>
</figure>
{% endfor %}

CodePudding user response：

that's because:

Product.objects.get(slug=slug) returns a single object type porduct. and one single object is not iterable

and

Product.objects.filter(slug=slug) returns a Queryset[] of products (list of products)

so if you are looking to treat multiple products use the second way, but if you are looking to treat one single product, use the first one
